Abstract
An evolutionary control for a subject such as an engine installed in a vehicle is conducted by the steps of: selecting coefficients, as genes, affecting the control characteristics of the control system; creating plural control units as chromosomes, each being constituted by plural genes; expressing the genes of each chromosome as control characteristics by conducting behavioral simulation on each chromosome; selecting at least one chromosome from the created chromosomes based on the result of the behavioral simulation; and causing the at least one chromosome to evolve using a genetic algorithm, thereby obtaining control characteristics suitable for the user. In this method, the characteristics of the product can easily be adjusted after its purchase.
