Quantum Monte Carlo encompasses a large family of computational methods whose common aim is the study of complex quantum systems.
 One of the major goals of these approaches is to provide a reliable solution (or an accurate approximation) of the quantum many-body problem.
 The diverse flavor of quantum Monte Carlo approaches all share the common use of the Monte Carlo method to handle the multi-dimensional integrals that arise in the different formulations of the many-body problem.
 The quantum Monte Carlo methods allow for a direct treatment and description of complex many-body effects encoded in the wave function, going beyond mean field theory and offering an exact solution of the many-body problem in some circumstances.
 In particular, there exist numerically exact and polynomially-scaling algorithms to exactly study static properties of boson systems without geometrical frustration.
 For fermions, there exist very good approximations to their static properties and numerically exact exponentially scaling quantum Monte Carlo algorithms, but none that are both.
Monte Carlo (] ; French: "Monte-Carlo" , ] , or colloquially "Monte-Carl", ] ; Monégasque: "Monte-Carlu") officially refers to an administrative area of the Principality of Monaco, specifically the ward of Monte Carlo/Spélugues, where the Monte Carlo Casino is located.
 Informally the name also refers to a larger district, the Monte Carlo Quarter (corresponding to the former municipality of Monte Carlo), which besides Monte Carlo/Spélugues also includes the wards of La Rousse/Saint Roman, Larvotto/Bas Moulins, and Saint Michel.
 The permanent population of the ward of Monte Carlo is about 3,500, while that of the quarter is about 15,000.
 Monaco has four traditional quarters.
 From west to east they are: Fontvieille (the newest), Monaco-Ville (the oldest), La Condamine, and Monte Carlo.

In chemistry, dynamic Monte Carlo (DMC) is a Monte Carlo method for modeling the dynamic behaviors of molecules by comparing the rates of individual steps with random numbers.
 It is essentially the same as Kinetic Monte Carlo.
 Unlike the Metropolis Monte Carlo method, which has been employed to study systems at equilibrium, the DMC method is used to investigate non-equilibrium systems such as a reaction, diffusion, and so-forth (Meng and Weinberg 1994).
 This method is mainly applied to analyze adsorbates' behavior on surfaces.
 The DMC method is very similar to the kinetic Monte Carlo method.
