BCA and HRA: Two Programs for Computing Economic Equilibria

This report gives programmers information useful for the utilization and modification of BCA and HRA, two programs for computing economic equilibria. The BCA implements the bilinear complementarity algorithm and HRA a homotopy retraction algorithm. The report describes the subroutines and variables used as well as the usual documentation: input format, sample input and output for two problems, and program listings. (Author).
