MEPX can be used to determine relationships between data. You have to provide it some training data in the form of pairs (input, output) and MEPX will discover a computer program which connects the input with the output.
MEPX is based on a Genetic Programming (GP) variant named Multi Expression Programming (MEP). MEP has a unique feature: it encodes multiple solutions in the same chromosome. This means that one can explore the search space more efficiently than other GP techniques encoding only one solution in a chromosome.
MEPX is available for download from here: www.mep.cs.ubbcluj.ro.
