A new version of the multi-dimensional integration and event generation package BASES/SPRING Original Research Article

The Monte Carlo integration and event generation package BASES/SPRING V1.0 S. Kawabata, Comput. Phys. Commun. 41 (1986) 127, has been upgraded so as to generate events with 50 independent variables, and to integrate functions with an alternating sign. Its ability to integrate real functions with indefinite sign is found to be useful in the numerical evaluation of interference effects among various amplitudes. Besides these changes, its program structure has been completely reformed.
