Control variates are a well-established tool to reduce the variance of Monte Carlo estimators. However, for large-scale problems including high-dimensional and large-sample settings, their advantages can be outweighed by substantial computational cost. This paper considers control based on Stein operators, presenting framework that encompasses generalizes existing approaches use polynomials, ke...

The Zori 1.0 package for electronic structure computations is described. Zori performs variational and diffusion Monte Carlo computations as well as correlated wave function optimization. This article presents an overview of the implemented methods and code capabilities.

In this paper, we propose a new optimization method based on the Monte Carlo method. The proposed is applied to several benchmark problems, and result of applying it neural network reported. Deep machine learning using networks one important keywords promote innovation in today’s advanced information society. Therefore, research large-scale, high-speed, high-precision algorithms has been active...

background: because of the adverse effects of ionizing radiation on fetuses, prior to radiotherapy of pregnant patients, fetal dose should be estimated. fetal dose has been studied by several authors in different depths in phantoms with various abdomen thicknesses (at). in this study, the effect of maternal at and depth in fetal dosimetry was investigated, using peripheral dose (pd) distributio...
