Random Seed Files:
SeedMaker.exe was written to identify the random seeds used to generate uniform random variates in SELDM. It generates a set of random variates, calculates statistics, and outputs each random-seed pair with the maximum deviation from theoretical uniform random variate statistics (see appendix 1).
