Abstract:
In the similar trajectory method (STM), the numerical-statistical modeling of trajectories of particles (radiation quanta) is implemented by applying an auxiliary radiation model. Weighted estimates of the functionals are calculated simultaneously for a set physical parameters values. Theoretical and numerical aspects of choosing an auxiliary model with the aim of minimizing the parametric maximum of the mean-square error in weighted estimates are discussed. Previously known results concerning minimax STM algorithms are refined, and new assertions are obtained. The STM is used to numerically study the parametric dependence of the “transport approximation” error for the particle transmission, absorption, and reflection probabilities.
Key words:
Monte-Carlo method, similar trajectory method, minimax algorithms.
