Abstract:
ii Abstract In this project, an unknown system structure was identified using the Genetic Programming technique. A program was developed that, instead of combining linear systems, evolves nonlinear ordinary differential equations to describe a system. The solution space was increased by using this approach. Automatically defined functions were used to represent the ordinary differential equations. A new way was introduced to speed up the evolution of genetic trees. The genetic trees representing the equations were written in C notation to a file to be compiled by a C compiler and evaluated by the computer. This required modifications to the Genetic Programming kernel formerly used. The modifications facilitated evaluation of a complete generation at one time to minimise compiler overhead. In order to build up a C++ class hierarchy, the kernel was completely restructured. A lot of features like shrink mutation, variable tournament size, improved deme handling etc. were also added.
