Download rho-mu JAR 4.2.0 with all dependencies

The rho mu library is a library of Randomization enHancements and Other Math Utilities. It includes implementations of various algorithms for randomly sampling indexes into arrays and other sequential structures, randomly sampling pairs and triples of unique indexes, randomly sampling k indexes, etc. It also includes efficient implementations of random number generation from distributions other than uniform, such as Gaussian, Cauchy, etc. Additionally, it includes implementations of other math functions that are either needed by the randomization utilities, or needed by some of our other projects.
