Currently, tools in the field of genetic programming are either geared towards solving certain type of problems, or are not easy to use (e.g., requiring actual source code modification of the software packages in order to generate a genetic programming environment). In addition, the solutions generated by existing tools are usually not ready for deployment in applications. In this paper, we describe a genetic programming tool called GP-Lab. GP-Lab is based upon, and an extension to an earlier tool reported in [13-14, 20]. GP-Lab supports a full and extensible programming language, and allows solutions to be automatically generated in C++ source code format ready to be compiled for deployment. It is a general tool and has many user-flexible features, including contextually aware genetic operations and graphic outputs.
