摘要：

A Monte Carlo program solving the Boltzmann equation for partons via the cascade method is presented. At presented, only gluon-gluon elastic scattering is included. The scattering cross section is regulated by a medium generated screening mass. Three different geometric modes (3-dimensional expansion, 1-d expansion, and scattering inside a box) are provided for both the theoretical study of parton transport and the application of the cascade method. Space cell division is available to save the number of computer operations. This improves the speed of the calculation by a large factor and makes the code best optimized for simulation of parton cascade in ultrarelativistic heavy ion collisions.
