This file describes how to use a series of programs written to implement the estimates given in Random weighting, asymptotic counting and inverse isoperimetry , by Alexander Barvinok and Alex Samorodnitsky. The programs are given by Alexander Yong (email: ayong@umich.edu). Please report and suggestions or bugs. We use implementations of the Hungarian algorithm (LAP code due to R. Jonker and A. Volgenant, email: roy_jonker@majiclogic.com) and H. Gabow's N-cubed weighted perfect matching algorithm, written by Ed Rothberg, found at: ftp://ftp.zib.de/pub/Packages/mathprog/matching/weighted/index.html
