A Common Lisp framework for experimenting with meta-optimizing semantic evolutionary search ([http://metacog.org/doc.html MOSES]) and related approaches to learning with probability distributions over program spaces based on: * reduction to normal form * representation-building * deme (su...

Meta-optimizing semantic evolutionary search (MOSES) is a new approach to program evolution, based on representation-building and probabilistic modeling. MOSES has been successfully applied to solve hard problems in domains such as computational biology, sentiment evaluation, and agent control. Resu...
