Tree chromosome structure in a genetic algorithm to identify functions

There are two main points in this paper. First, the tree structure was mounted on the chromosome structure of a simple GA. Next, this method succeeded in identifying functions. The target functions for identification were composed of algebraic functions, primary transcendental functions, time series functions, and user-defined one-variable functions. The experimental results indicate that identification of expanded functions succeeded at high speed. However, functions were not identified in factorized form. A second solution method is proposed and experimental results described. © 2000 Scripta Technica, Syst Comp Jpn, 31(10): 32–40, 2000
