Co-evolutionary Automatic Defined Functions Approach and Applications in GP Algorithm
Sichun Wang · Jisuanji yingyong yanjiu · 2005
Co-Automatically defined functions technique consists of evolving a number of separate sub-populations of functions which can be used by a population of evolving main programs. We present and refine a set of mechanisms by which the number and constitution of the function sub-populations can be defined and compare their performance on two well-known classification tasks. A final version of the general approach, for use explicitly on classification tasks, is then presented. It is shown that the coevolutionary approach performs better than traditional genetic programming with and without ADFs.
