description: We present the results of a multiline survey at mm-wavelengths of the Cepheus A star forming region. Four main flows have been identified: three pointing in the SW, NE, and SE directions and accelerating high density CS clumps. The fourth outflow, revealed by high-sensitivity HDO observations, is pointing towards South and is associated with conditions particularly favourable to a chemical enrichment. The analysis of the line profiles shows that the SiO molecule dominates at the highest velocities and at the highest excitation conditions, confirming its close association with shocks. H2S, SO2, and SO preferentially trace more quiescent regions than SiO, and in particular a lack of bright H2S emission at the highest velocities is found. OCS and H2CS emit at quite high velocities, where the abundances of three shock tracers like SiO, CH3OH, and HDO are higher. These results may indicate that H2S is not the only major sulphur carrier in the grain mantles, and that OCS and H2CS may probably play an important role on the grains; or that alternatively they rapidly form once the mantle is evaporated after the passage of a shock. Finally, the outflow peak emission has been compared with recent time-dependent sulphur chemistry models: the results indicate that, if associated with accurate measurements of the physical conditions, the CH3OH/H2CS column density ratio can be used as an effective chemical clock to date the age of shocked gas.

description: Biocatalytic oxidation reactions are in high demand. Among the applied enzymes, the heme-thiolate enzyme subfamily of unspecific peroxygenases (UPOs), which relies on hydrogen peroxide as cosubstrate and oxidant, has generated great interest. Almost two decades after their first description, databases provide thousands of putative UPO sequences, but only a few enzymes have been characterized. To address this gap, efficient screening methods for the identification of novel UPOs are necessary. Here, a new screening strategy is presented based on solid cultivation of wild-type fungi. The identification of a promising candidate strain highlights the applicability of this approach.

description: To solve the problem of exact integration of the field equations or equations of motion of matter in curved spacetimes one can use a class of Riemannian metrics for which the simplest equations of motion can be integrated by the complete separation of variables method. Here, we consider the particular case of the class of Stackel metrics. These metrics admit integration of the Hamilton-Jacobi equation for test particle by the complete separation of variables method. It appears that the other important equations of motion (Klein-Gordon-Fock, Dirac, Weyl) in curved spacetimes can be integrated by complete separation of variables method only for the metrics, belonging to the class of Stackel spaces.

description: Fabricating 3D printed electronics using desktop printers has become more accessible with recent developments in conductive thermoplastic filaments. Because of their high resistance and difficulties in printing traces in vertical directions, most applications are restricted to capacitive sensing. In this paper, we introduce Thermoformed Circuit Board (TCB), a novel approach that employs the thermoformability of the 3D printed plastics to construct various double-sided, rigid and highly conductive freeform circuit boards that can withstand high current applications through copper electroplating. To illustrate the capability of the TCB, we showcase a range of examples with various shapes, electrical characteristics and interaction mechanisms. We also demonstrate a new design tool extension to an existing CAD environment that allows users to parametrically draw the substrate and conductive trace, and export 3D printable files. TCB is an inexpensive and highly accessible fabrication technique intended to broaden HCI researcher participation.

A pure spin current, where oppositely oriented spins move in opposite directions, can be injected in zincblende crystals and structures. The calculated spin current should be detectable by pump-probe optical spectroscopy and anomalous Hall effect measurement.

description: Acoustically actuated sessile bubbles can be used as a tool to manipulate microparticles, vesicles and cells. In this work, using acoustically actuated sessile semi-cylindrical microbubbles, we demonstrate experimentally that finite-sized microparticles undergo size-sensitive migration and trapping towards specific spatial positions in three dimensions with high reproducibility. The particle trajectories are successfully reproduced by passive advection of the particles in a steady three-dimensional streaming flow field augmented with volume exclusion from the confining boundaries. For different particle sizes, this volume exclusion mechanism leads to three regimes of qualitatively different migratory behavior, suggesting applications for separating, trapping, and sorting of particles in three dimensions.

description: We demonstrate that two mechanisms used by biological ion channels to select particles by size are driven by entropy. With uncharged particles in an infinite cylinder, we show that a channel that attracts particles is small-particle selective and that a channel that repels water from the wall is large-particle selective. Comparing against extensive density-functional theory calculations of our model, we find that the main physics can be understood with surprisingly simple bulk models that neglect the confining geometry of the channel completely.

description: We introduce a new augmented adaptation of the recently developed full coupled-cluster reduction (FCCR) with a second-order perturbative correction, abbreviated as FCCR(2). FCCR is a selected coupled-cluster expansion aimed at optimally reducing the excitation manifold and commutator expansions for high-rank excitations to obtain accurate solutions of the electronic Schrodinger equation in a size-extensive manner. The present FCCR(2) enables the estimation of the residual correlation of FCCR by the second-order perturbative correction $E^{(2)}$ from the complementary space of the FCCR projection manifold. The linear relationship between $E^{(2)}$ and the energy of FCCR(2) allows accurate estimates of near-exact energies for a wide variety of molecules with strong electron correlations. The potential of the method is demonstrated using challenging cases, such as the ground state electronic energy of the benzene molecule in equilibrium and stretched geometries, and the isomerization energy of the transition metal complex, [Cu(NH$_3$)]$_2$O$_2$$^{2+}$.

description: We build rigorously the attractive five-dimensional model where bulk fermions propagate along the $ \mathcal{S}^1 / \mathbb{Z}_2$ orbifold and interact with a Higgs boson localised at a fixed point of the extra dimension. The analytical calculation of the fermion mass spectrum and effective Yukawa couplings is shown to require the introduction of either Essential Boundary Conditions (EBC) imposed by the model definition or certain Bilinear Brane Terms (BBT) in the action, instead of the usual brane-Higgs regularisations. The obtained fermion profiles along the extra dimension turn out to undergo some discontinuities, in particular at the Higgs brane, which can be mathematically consistent if the action is well written with improper integrals. We also show that the $\mathbb{Z}_2$ parity transformations in the bulk do not affect the fermion chiralities, masses and couplings, in contrast with the EBC and BBT, but when extended to the fixed points, they can generate the chiral nature of the theory and even select the Standard Model chirality set-up while fixing as well the fermion masses and couplings. Thanks to the strict analysis developed, the duality with the interval model is scrutinised.

The data cover a broad range of isotopes of the elements between Z = 3 and Z = 56 for 136Xe and between Z = 5 and Z = 55 for 124Xe, reaching down to cross sections of a few microbarns. The velocity distributions exhibit a Gaussian shape for masses above A = 20, while more complex behaviour is observed for lighter masses. The isotopic distributions for both reactions preserve a memory on the projectile N/Z ratio over the whole residue mass range.

description: The three-dimensional secular behavior of a system composed of a central star and two massive planets is modeled semi-analytically in the frame of the general three-body problem. The main dynamical features of the system are presented in geometrical pictures allowing us to investigate a large domain of the phase space of this problem without time-expensive numerical integrations of the equations of motion and without any restriction on the magnitude of the planetary eccentricities, inclinations and mutual distance. Several regimes of motion of the system are observed. With respect to the secular angle $Δ\varpi$, possible motions are circulations, oscillations (around 0 and $180^\circ$), and high eccentricity/inclination librations in secular resonances. With respect to the arguments of pericenter, $ω_1$ and $ω_2$, possible motions are direct circulation and high-inclination libration around $\pm 90^\circ$ in the Lidov-Kozai resonance. The regions of transition between domains of different regimes of motion are characterized by chaotic behavior. We apply the analysis to the case of the two outer planets of the $\upsilon$ Andromedae system, observed edge-on. The topology of the 3--D phase space of this system is investigated in detail by means of surfaces of section, periodic orbits and dynamical spectra, mapping techniques and numerical simulations. We obtain the general structure of the phase space, and the boundaries of the spatial secular stability. We find that this system is secularly stable in a large domain of eccentricities and inclinations.

description: Il sistema contributivo per simmorie presente ad Atene nel IV secolo a.C. è al centro di un ampio dibattito che cerca di definirne struttura e funzionamento, alla luce di poche testimonianze storiche esistenti al riguardo. Questo articolo sostiene il valore documentario dell'orazione Sulle Simmorie di Demostene: essa, illustrando un piano di riforma per il finanziamento della marina da guerra, offre una descrizione tecnica e precisa del sistema simmorico. L'esame puntuale di tre passi del discorso induce a ritenere che nel IV secolo a.C. la trierarchia adottasse il metodo contributivo tipico dell'eisphora, assumendo uno statuto intermedio tra liturgia e imposta.

The contributive system by symmories used in Athens in the Fourth century B.C. is the focus of a long debate, that wants to define its structure and functioning, on the basis of few documents existing about it. This article demonstrates the documentary value of Demosthenes’ oration On the symmories: explaining a reform plan to finance Athenian navy, it makes a technical and precise description of symmoric system. The detailed analysis of three passages of the discourse suggests that in Fourth century B.C. the trierarchy was financed by the contributive method of eisphora, taking an intermediate status between a liturgy and a tribute.

La manomissione al femminile. Sulla capacità economica delle donne in Grecia in età ellenistica: l'apporto degli atti di affrancamento

Subjects: donne; manomissione

description: Nel contributo si vogliono considerare alcuni aspetti della capacità economica delle donne dell'età ellenistica, prendendo in analisi specificatamente i dati offerti dagli atti di emancipazione, ove esse compaiono essenzialmente in tre diversi ruoli: come manomissori o co-manomissori, come coloro che danno il consenso tramite la syneudoke oppure come schiave affrancate. In particolare, alcune iscrizioni provenienti dalla Grecia centrale e settentrionale evidenziano la possibilità, per le donne, di manomettere i propri schiavi senza la presenza del kyrios. Tra le affrancatrici non è raro trovare anche ex-schiave e donne di condizione sociale bassa, come dimostra, ad esempio, l’iscrizione IG IX 1² 3, 755 (Anfissa). Ad alcune manomesse, inoltre, in aggiunta alla libertà, sembrano esser concessi benefici economici importanti, come il possesso di beni e dimora (IG IX 2, 1290) o anche, a mio giudizio, la possibilità di gestire il proprio patrimonio in autonomia (e. g. SGDI 1718).

In the article, we want to consider some aspects linked to the women’s economic life in the Hellenistic period, giving a special attention to the data offered by the manumission inscriptions, where women can have three different roles: they can be slave owners, “the ones who give the agreement” through the syneudoke or freedwomen. In particular, some inscriptions  from central and northern  Greece show the opportunity held by women to manumit their slaves without a kyrios. Among the manumittors we can find even former slaves and women in a low social position, as, for instance, the inscription IG IX 1² 3, 755 from Amphissa shows. Moreover, if I am right, some important economic benefits seem to be given to some freedwomen in addition to freedom, like the chance of keeping goods and a house (IG IX 2, 1290) or even the opportunity of managing their own properties (e. g. SGDI 1718).

description: L’autore esamina il problema rappresentato dai documenti epigrafici che conservino liste di nomi. La loro natura rimane talvolta incerta a causa dell’assenza di intestazioni, scomparse per la lacunosità del supporto scrittorio; in altri casi la carenza di elementi interni al testo non consente un’attribuzione affidabile. L’unico criterio che può essere perseguito nella discussione di tali iscrizioni riguarda la forma della citazione onomastica, che pare caratterizzare alcune serie documentarie. Un documento proveniente da Lemnos presenta una lista di semplici nomi, non accompagnati da alcun altro determinativo onomastico, su cui permane l’incertezza esegetica. Si possono tuttavia avanzare osservazioni interessanti sull’individuo citato alla linea 10, i cui legami famigliari non paiono ignorabili. Il livello della famiglia sembra rientrare tra gli strati emergenti della società ateniese.

The author examines the problem represented by the epigraphic documents with lists of names. Their nature is sometimes uncertain due to the absence of headers, which are disappeared because of the incomplete writing surface; in other cases, the lack of elements within the text does not allow a reliable attribution. The only criterion that can be pursued in the discussion of these inscriptions is the onomastic formulation’s form, which seems to characterize some documentary series. A document from Lemnos presents a list of simple names, unaccompanied by any other onomastic determination, on which the exegesis remains uncertain. It is possible, however, to propose interesting observations on the individual cited in line 10, whose family bonds do not seem ignorable. The level of the family seems to be part of the emerging layers of the Athenian society.

description: The canonical $Λ$CDM cosmological model makes precise predictions for the clustering and lensing properties of galaxies. It has been shown that the lensing amplitude of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) is lower than expected given their clustering properties. We present new measurements and modelling of galaxies in the BOSS LOWZ sample. We focus on the radial and stellar mass dependence of the lensing amplitude mis-match. We find an amplitude mis-match of around $35\%$ when assuming $Λ$CDM with Planck Cosmological Microwave Background (CMB) constraints. This offset is independent of halo mass and radial scale in the range $M_{\rm halo}\sim 10^{13.3} - 10^{13.9} h^{-1} M_\odot$ and $r=0.1 - 60 \, h^{-1} \mathrm{Mpc}$ ($k \approx 0.05 - 20 \, h \, {\rm Mpc}^{-1}$). The observation that the offset is both mass and scale independent places important constraints on the degree to which astrophysical processes (baryonic effects, assembly bias) can fully explain the effect. This scale independence also suggests that the "lensing is low" effect on small and large radial scales probably have the same physical origin. Resolutions based on new physics require a nearly uniform suppression, relative to $Λ$CDM predictions, of the amplitude of matter fluctuations on these scales. The possible causes of this are tightly constrained by measurements of the CMB and of the low-redshift expansion history.

description: Abstract

L’articolo indaga il contesto delle riforme di L. Apuleio Saturnino (103-100 a.C.) e la rielaborazione, a fini politici, del mito dei Gracchi. Le leges Apuleiae si presentano come una ripresa della legislazione graccana, di cui imitano scopi e contenuti. All’interno di questo processo, è possibile individuare un’attenzione particolare dei riformatori per il territorio transpadano occidentale. L’articolo ipotizza che la fondazione della colonia di Eporedia sia un modo con cui i populares mariani si riappropriarono del territorio transpadano dopo un decennio di smantellamento delle riforme graccane: l’apertura dei libri sibillini al momento della deduzione della colonia va letta nell’ottica del precedente di Appio Claudio Pulcro e costituisce un argomento per attribuire la colonia ai populares.

This paper investigates the context laying beyond L. Apuleius Saturninus’ reforms (103-100 a.C.) and the political construction of the myth of the Gracchi. The leges Apuleiae are presented as a resumption of gracchan laws and imitate their contents and aims. A special attention of the reformers on western Traspadana can be seen in this process. The article presents the hypothesis that the foundation of Eporedia was the mean that Marius’ populares used to reaffirm their presence in the area after ten years of dismantling of gracchan reforms. The opening of libri sibyllini before the foundation of the colony can be considered a citation of Appius Claudius Pulcher’s precedent and an evidence to interpret the colony as popularis.

Time delay compensation of digital control for switchmode DC power supplies using prediction techniques
Creators: name: Bibian, Stéphane
Publisher: name: University of British Columbia
Year: 2009

description: The control of switchmode dc power supplies has been traditionally implemented in analog electronics for its low cost, high bandwidth, and proven technology. However, the emergence of advanced microprocessors and Digital Signal Processors (DSPs) has made it possible for power supply manufacturers to consider digital technology a suitable option. As compared to analog control, digital control provides a number of advantages such as reduced susceptibility to aging and environmental variation (temperature, humidity, etc.), better noise immunity, ability to handle complex control schemes and monitoring functions, possibility to implement communication functions for fault and status information, and easy re-programming for different applications. With the downward trend of microprocessor prices and the versatility of the hardware architecture, digital control offers a cost-effective solution which can compete with analog technology. However, one of the major drawbacks of digital control is the limited bandwidth caused by the inherent time delay required for A/D conversion, computation and PWM generation. Such delay degrades the control loop performance, which makes it difficult to comply with technical specifications in many high-performance products. In this thesis, a simple and straightforward predictive technique based on linear extrapolation is presented to compensate for this delay. Two predictive controllers are derived and applied to a full bridge dc power supply. Simulation and experimental results show that the performances of the converter with respect to dc bus ripple and load disturbances can be significantly improved. Those schemes are characterized by a low computational cost which makes them particularly attractive in the demanding real-time environment due to the ever increasing switching frequency of the converter. A similar prediction concept based on a second order parabolic extrapolation is also presented. This predictor substantially reduces the amount of calculation needed to obtain similar results to a conventional controller, thus freeing valuable processor resources. These resources can be used for less critical tasks such as communication and user interface. As a result, the processor is not solely dedicated to the control of the power supply but can incorporate other functions, thus adding functionality and expandability to the system. Finally, this thesis assesses typical digital control issues such as word length, A/D resolution and fixed point programming.

To do so, we consider a string embedding and study its fluctuations which do not admit Liouville integrable solutions. We, also, perform a numerical analysis to study the time evolution of the string and compute the largest Lyapunov exponent. This analysis indicates that the string motion is chaotic. Finally, we consider the point-like limit of the string that corresponds to BPS mesons of the quiver theory.

It is found that the conductance oscillates with both of the coupling strength and length. The corresponding local density of states (LDOS) is clearly shown and can be used to explain the reason why there are such kinds of oscillations of the conductances, which should be noted in the design of nanotube-based devices.

description: The Square Kilometre Array (SKA) project is an international effort to build the world s largest radio telescope, enabling science with unprecedented detail and survey speed. The project spans over a decade and is now at a mature stage, ready to enter the construction and integration phase. In the fully deployed state, the MID-Telescope consists of a 150-km diameter array of offset Gregorian antennas installed in the radio quiet zone of the Karoo desert (South Africa). Each antenna is equipped with three feed packages, that are precision positioned in the sub-reflector focus by a feed indexer platform. The total observational bandwidth (0.35-15.4GHz) is segmented into seven bands. Band 1 (0.35-1.05GHz) and Band 2 (0.95-1.76GHz) are implemented as individual feed packages. The remaining five bands (Bands 3, 4, 5a, 5b, and 6) are combined in a single feed package. Initially only Band 5a (4.6-8.5GHz) and Band 5b (8.3-15.4GHz) will be installed. This paper provides an overview of recent progress on design, test and integration of each feed package as well as project and science goals, timeline and path to construction.

description: Event sequence data is increasingly available in various application domains, such as business process management, software engineering, or medical pathways. Processes in these domains are typically represented as process diagrams or flow charts. So far, various techniques have been developed for automatically generating such diagrams from event sequence data. An open challenge is the visual analysis of drift phenomena when processes change over time. In this paper, we address this research gap. Our contribution is a system for fine-granular process drift detection and corresponding visualizations for event logs of executed business processes. We evaluated our system both on synthetic and real-world data. On synthetic logs, we achieved an average F-score of 0.96 and outperformed all the state-of-the-art methods. On real-world logs, we identified all types of process drifts in a comprehensive manner. Finally, we conducted a user study highlighting that our visualizations are easy to use and useful as perceived by process mining experts. In this way, our work contributes to research on process mining, event sequence analysis, and visualization of temporal data.

description: The mean and the scatter of the HI content of a dark-matter halo as a function of the halo mass are useful statistics that can be used to test models of structure and galaxy formation. We investigate the possibility of constraining this HI-halo mass relation (HIHMR) from intensity maps of the redshifted 21 cm line. In particular, we use the geometry and topology of the brightness-temperature isocontours in a single frequency channel as quantified by the Minkowski functionals. First, we generate mock maps from a large N-body simulation considering the impact of thermal noise and foreground removal. We then use the Fisher information formalism to forecast constraints on a parametric model for the HIHMR. We consider a 20,000 deg$^2$ survey (originally proposed for dark-energy science) conducted with the Square Kilometre Array Phase 1 (SKA-1) MID observatory operating in single-dish mode. For a channel bandwidth of 2 MHz, we show that an integration time of a few$\,\times\,10^4$ s per pointing is sufficient to image the smoothed HI distribution at redshift $z \simeq 1$ and to measure the HIHMR in a nearly optimal way from the Minkowski functionals. Tighter constraints on some of the parameters can be obtained by using also an independent measurement of the mean HI density. Combining the results from different frequency channels provides exquisite constraints on the evolution of the HIHMR, especially in the central frequency range of the data cube.

description: Abstract

Nel periodo tra la tarda età repubblicana e il principato di Augusto l’area nella quale si esercitava l’influenza politica ed economica di Roma si estese notevolmente su vasti territori sia a nord quanto a sud delle Alpi orientali. Già in età repubblicana in seguito alle campagne militari di Cesare, commercianti nord italici si erano mossi verso oriente trasferendosi nell’insediamento transalpino di Nauportus al fine di utilizzare le opportunità offerte dai fiumi Ljubljanca, Sava e Danubio. Nel corso del I secolo d.C., la città di Emona, anche essa parte della X Regio, rimpiazzò Nauportus come punto di entrata in Italia delle linee di comunicazione con le province orientali. Questo contributo cerca di chiarire le connessioni delle gentes aquileiesi con gli insediamenti transalpini di Nauportus ed Emona cercando di stabilire se i cambiamenti nella gerarchia di importanza degli insediamenti influenzarono l’attività e l’importanza delle famiglie coinvolte.

From the last decades of the republican period and the beginning of the Augustean rule Rome’s political control had extended over large territories both north and south of the Oriental Alps. During the period of the late Republic already, following Caesar’s military campaigns, north-italic settlers and traders moved eastwards in the transalpine settlement of Nauportus, on the eastern side of the Alps, in order to exploit the trade possibilities provided by the rivers Ljubljanica, Sava and Danube. In the 1st century AD, Emona, a town also belonging to the X Regio of Italy, became the prominent centre in the connections with the Eastern provinces taking quickly the place of Nauportus as the terminal of the oriental trade routes before the Alps. This short contribution aims to shed light on the family connections and on the presence of different Aquileian (and other north Italian) families east of the Alps, in particular in the centers of Nauportus and Emona, trying to establish whether the increase of importance of the latter affected the economic activity and the importance of the Aquileian families involved.

description: The ability to accurately track what happens during a conversation is essential for the performance of a dialogue system. Current state-of-the-art multi-domain dialogue state trackers achieve just over 55% accuracy on the current go-to benchmark, which means that in almost every second dialogue turn they place full confidence in an incorrect dialogue state. Belief trackers, on the other hand, maintain a distribution over possible dialogue states. However, they lack in performance compared to dialogue state trackers, and do not produce well calibrated distributions. In this work we present state-of-the-art performance in calibration for multi-domain dialogue belief trackers using a calibrated ensemble of models. Our resulting dialogue belief tracker also outperforms previous dialogue belief tracking models in terms of accuracy.

description: The ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey and the 2dF Galaxy Redshift Survey (2dFGRS) respectively comprise the largest, homogeneous X-ray selected cluster catalogue and completed galaxy redshift survey. In this work we combine these two outstanding datasets in order to study the effect of the large-scale cluster environment, as traced by X-ray luminosity, on the properties of the cluster member galaxies. We measure the LX-sigma relation from the correlated dataset and find it to be consistent with recent results found in the literature. Using a sample of 19 clusters with LX>=0.36*10^44 erg s^-1 in the (0.1-2.4 keV) band, and 49 clusters with lower X-ray luminosity, we find that the fraction of early spectral type (eta<=-1.4), passively-evolving galaxies is significantly higher in the high-LX sample within R200. We extend the investigation to include composite bJ cluster luminosity functions, and find that the characteristic magnitude of the Schechter-function fit to the early-type luminosity function is fainter for the high-LX sample compared to the low-LX sample (Delta M*=0.58+/-0.14). This seems to be driven by a deficit of such galaxies with M_bJ ~ -21. In contrast, we find no significant differences between the luminosity functions of star-forming, late-type galaxies. We believe these results are consistent with a scenario in which the high-LX clusters are more dynamically evolved systems than the low-LX clusters.

description: The relaxation of a classical spin, exchange coupled to the local magnetic moment at an edge site of the one-dimensional spinful Su-Schrieffer-Heeger model is studied numerically by solving the full set of equations of motion. A Lindblad coupling of a few sites at the opposite edge to an absorbing bath ensures that convergence with respect to the system size is achieved with only a moderate number of core sites. This allows us to numerically exactly study the long-time limit and to determine the parameter regimes where spin relaxation takes place. Corresponding dynamical phase diagrams for the topologically trivial and the nontrivial cases are constructed. The dynamical phase boundaries, the role of the topological edge state and its internal Zeeman splitting for the spin-relaxation process, as well as incomplete spin relaxation on long time scales can be explained within the framework of a renormalized linear-response approach when explicitly taking retardation effects and nonequilibrium spin-exchange processes into account.

description: This study analyzes performance of several genetic and evolutionary algorithms on randomly generated NK fitness landscapes with various values of n and k. A large number of NK problem instances are first generated for each n and k, and the global optimum of each instance is obtained using the branch-and-bound algorithm. Next, the hierarchical Bayesian optimization algorithm (hBOA), the univariate marginal distribution algorithm (UMDA), and the simple genetic algorithm (GA) with uniform and two-point crossover operators are applied to all generated instances. Performance of all algorithms is then analyzed and compared, and the results are discussed.
