TL;DR: An adaptative variance reduction method for Monte Carlo simulations that uses importance sampling scheme based on a change of drift and develops two applications of the procedure for variance reduction in a Monte Carlo computation in finance and in reliability.
Abstract: In this article we propose an adaptative variance reduction method for Monte Carlo simulations. The method uses importance sampling scheme based on a change of drift. The change of drift is selected adaptatively through the Monte Carlo computation by using a suitable sequence of approximation. We state and prove theoretical results supporting the use of the method. We develop two applications of the procedure for variance reduction in a Monte Carlo computation in finance and in reliability.

TL;DR: A cross-disciplinary survey on “population” Monte Carlo algorithms, a set of “walkers” or “particles” is used as a representation of a high-dimensional vector in these algorithms, discussed in a coherent framework.
Abstract: We give a cross-disciplinary survey on “population” Monte Carlo algorithms.In these algorithms, a set of “walkers” or “particles” is used as a representation of a high-dimensional vector. The computation is carried out by a random walk and split/deletion of these objects. The algorithms are developed in various fields in physics and statistical sciences and called by lots of different terms — “quantum Monte Carlo”, “transfer-matrix Monte Carlo”, “Monte Carlo filter (particle filter)”, “sequential Monte Carlo” and “PERM” etc. Here we discuss them in a coherent framework. We also touch on related algorithms —genetic algorithms and annealed importance sampling.

TL;DR: In this article, a new method for employed electron-electron (e-e) and electron-ion (ei) interactions in Monte Carlo particle based simulators is presented.
Abstract: A new method for employed electron-electron (e-e) and electron-ion (e-i) interactions in Monte Carlo particle based simulators is presented. By using a corrected Coulomb force in conjunction with a proper cutoff range, the "double" counting of the long range interaction is eliminated while reducing the simulation time for molecular dynamics by a factor of 1000. The proposed method naturally incorporated the multi-ion contributions, local distortions in the scattering potential due to the movement of the free charges, and carrier-density fluctuations. The doping dependence of the low-field mobility obtained from three-dimensional (3-D) resistor simulation closely follows experimental results, thus proving the correctness of the proposed approach.

TL;DR: The techniques for calculation of the electronic structure of relatively large molecular systems with very high accuracy, from positron complexes to silicon crystal structures of 250 atoms and 1000 valence electrons are reviewed.
Abstract: Quantum Monte Carlo methods have recently made it possible to calculate the electronic structure of relatively large molecular systems with very high accuracy. These large systems range from positron complexes [NH2,Ps] with ∼10 electrons to C20 isomers with 120 electrons, to silicon crystal structures of 250 atoms and 1000 valence electrons. The techniques for such calculations and a sampling of applications are reviewed.
