Improved Monte-Carlo Search
Monte-Carlo search has been successful in many non-deterministic games, and recently in deterministic games with high branching factor. One of the drawbacks of the current approaches is that even if the iterative process would last for a very long time, the selected move does not necessarily converge to a game-theoretic optimal one. In this paper we introduce a new algorithm, UCT, which extends...
متن کاملNonlocal pseudopotentials and diffusion Monte Carlo
We have applied the technique of evaluating a nonlocal pseudopotential with a trial function to give an approximate, local many-body pseudopotential which was used in a valence-only diffusion Monte Carlo (DMC) calculation. The pair and triple correlation terms in the trial function have been carefully optimized to minimize the effect of the locality approximation. We discuss the accuracy and co...
متن کاملIntroduction to the Diffusion Monte Carlo Method
A self–contained and tutorial presentation of the diffusion Monte Carlo method for determining the ground state energy and wave function of quantum systems is provided. First, the theoretical basis of the method is derived and then a numerical algorithm is formulated. The algorithm is applied to determine the ground state of the harmonic oscillator, the Morse oscillator, the hydrogen atom, and ...
متن کاملBilinear diffusion quantum Monte Carlo methods.
The standard method of quantum Monte Carlo for the solution of the Schrödinger equation in configuration space can be described quite generally as devising a random walk that generates-at least asymptotically-populations of random walkers whose probability density is proportional to the wave function of the system being studied. While, in principle, the energy eigenvalue of the Hamiltonian can ...
متن کاملSequential Monte Carlo Methods for Diffusion Processes
In this paper we show how to use sequential Monte Carlo (SMC) methods ([7, 13]) to compute expectations of functionals of diffusions at a given time and the gradients of these quantities w.r.t the initial condition of the process. In some cases, using the exact simulation of diffusions methodology ([3]), there is no time discretization error, otherwise the methods use Euler discretization. We i...
