What Is Psh?

Psh is a Java implementation of the Push programming langage and of PushGP.

What Is Push? What is PushGP?

Push is a programming language designed specifically for genetic programming and other evolutionary computation applications. Push has an unusually simple syntax, which facilitates the development (or evolution) of mutation and recombination operators that generate and manipulate programs. Push also supports dynamic code manipulation and can support entirely new evolutionary computation paradigms such as "autoconstructive evolution," in which genetic operators and other components of the evolutionary system themselves evolve. PushGP is a genetic programming system built on top of Push. Push was developed by Lee Spector. More information about Push is available here.
