Foam: Multi-dimensional general purpose Monte Carlo generator with self-adapting simplical grid
Description
Abstract A new general purpose Monte Carlo event generator with self-adapting grid consisting of simplices is described. In the process of initialization, the simplex-shaped cells divide into daughter subcells in such a way that: (a) cell density is biggest in areas where integrand is peaked, (b) cells elongate themselves along hyperspaces where integrand is enhanced/singular. The grid is anisotropic, i.e. memory of the axes directions of the primary reference frame is lost. In particular, the algorit... Title of program: Foam, version 1.01 Catalogue Id: ADMC_v1_0.tar Nature of problem Monte Carlo (MC) simulation or generation of unweighted (weight equal one) events, is a standard exercise in the particle physics, and in many other areas of the research. It is often necessary to generate MC events according to a probability density with strong peaks (singularities) spanned along complicated hyperspaces of not a very well known shape. It is highly desirable to have in the program library a general-purpose numerical tool (program) with a MC generation algorithm featuring built-i ...
