The Limits of Estimation of Distribution Algorithms
Authors: Ding Cai Chang , Peng Wen Xiu , Wang Wei Ming
Published: May 2014

In this paper, we study the ability limit of EDAs to effectively solve problems in relation to the number of interactions among the variables. More in particular, we numerically analyze the learning limits that different EDA implementations encounter to solve problems on a sequence of additively decomposable functions (ADFs) in which new sub-functions are progressively added. The study is carried out in a worst-case scenario where the sub-functions are defined as deceptive functions. We argue that the limits for this type of algorithm are mainly imposed by the probabilistic model they rely on. Beyond the limitations of the approximate learning methods, the results suggest that, in general, the use of bayesian networks can entail strong computational restrictions to overcome the limits of applicability.

Published: May 2014

The limit equilibrium FEM method is a common method using the result of stresses fields obtained from numerical calculation to get resistant sliding force and driving sliding force on the dangerous sliding surface to analyze the stability of slope. The safety factor is the ratio of resistant sliding force to driving sliding force on the most dangerous sliding surface.When compares limit equilibrium FEM method with the rigid body limit equilibrium method, its applicability needs to be verified. Taking a project as an example, this work uses the two methods to analyze the stability of the slope. After calculating, two different safety factors on the sliding surface were got, and the reasons inducing the difference of the safety factors were analyzed. The result showed the safety factor calculated from the limit equilibrium FEM method is much closer to the real situation especially when some parts of the soil are in plastic state. It is mainly because the limit equilibrium FEM method takes the coordination of deformation into consideration. Then two conditions: nature and rain are calculated to analyzed the slope stability. It made a judgment of the stability of the slope and gave a beneficial conclusion to the project.

The process of open-pit mining can lead to high slopes in iron mines, and natural slopes should be rebuilt by the method of roof fall as the exploitation style turns from open-pit mining to the underground mining. So the slope can be steep, deep and may has the characteristics of collapse. It is difficult to describe the stabilization of the mining slope by a conventional safety factor method. Through the numerical simulation of underground mining process, this paper analyzes the result of distortion stress and rock movement rupture range. Studies have shown that the failure mode is dominated by tensile failure as a pattern of collapse and few is dominated by shear failure. The failure zone is controlled by rock mass parameters and structures. The results can be helpful for the proposition of exploitation program and safety management design.

The composition and origin of organic matter (OM) released form three PM10samples obtained from biomass and oil combustion was investigated in this study. The Py-GC/MS system was applied and experiments were conducted at 5 °C/min to 750 °C. A difference in the composition and therefore in OM between the examined samples was observed. The greatest variation in released compounds was noted for PM10sample obtained from biomass combustion. Whereas the least variation in composition was observed for PM10sample obtained from B oil sample. The latter consisted in majority of squalene (81.5 %). As a result, the quantity of OM released by the biomass sample was greater by 18.2 % and 33.9 % that the quantity released by A and B oil samples, respectively.

Authors: Yin Jiao Jiao
Published: May 2014

Because the reflectivity of astaxanthin vary in different bands (mainly 400nm-600nm), so we use the visible-near infrared spectra technique to irradiate the salmon. Because in daily life, people grade the salmon flesh with a color card. In this paper, we first use principal component analysis to reduce the dimensionality of the spectral data of salmon, then use linear discriminant analysis method, least squares support vector machine classification method to distinguish the flesh quality. The correct classification rates are 60%and73.3%. The results show that we can use visible – near infrared spectra to distinguish the quality of the salmon which doesn’t be dissected.
