GEMS Evolve Project Code

This repository contains ANSI common Lisp code for the core program generation system, providing a genetic programming library, experiment/model setup and analysis tools.

The project code is organised into two packages:

• (require 'gems) - provides the basic functionality. For convenience, the package is internally organised into sub-packages: builder, gems-logger, gpstats, mini-gp and syntax-tree. It requires alexandria.
• (require 'gems/tk) - includes the basic functionality in gems, and adds support for constructing graphical interfaces. It requires ltk and ltk-plotchart.

The project website is https://gems.codeberg.page

Install and Test

To use this code from source, download or clone and make gems available to the asdf system (depending on your installation and setup, this is done by copying or linking the "gems-evolve" directory to the appropriate directory: e.g. on Linux, ~/common-lisp/, or on Windows, C:\User\YOURNAME\common-lisp. Alternatively, if you are using portacle, copy "gems-evolve" into "portacle/projects".).

In addition, you will need to install:

• alexandria - by download or (ql:quickload :alexandria)
• ltk (for gems/tk) - by download or (ql:quickload :ltk)
• ltk-plotchart - by download

To test the system in a REPL:

* (asdf:test-system :gems)
