TinyGP1 i s a highly optimised GP system that was originally developed to meet the specifications set out in the TinyGP competition of the Genetic and Evolutionary Computation Conference (GECCO) 2004. We include it as a working example of a real GP system, to show that GP software tools are not necessarily big, complex and difficult to understand. The system can be used as is or can be modified or extended for a user's specific applications. Furthermore, TinyGP may serve as a guide to other implementations of genetic programming.
The following section provides a description of the main characteristics of TinyGP. Section B.2 describes the format for the input files for TinyGP. Section B.3 provides further details on the implementation and the source code for a Java version of TinyGP. Finally, Section B.4 describes a sample run of the system.
There are numerous other GP systems available on-line. See Section A.4 for a discussion of some of the options.
