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 controlling the subject using the control system having the control characteristics; selecting at least one chromosome from the created chromosomes based on the control characteristics expressed by the genes in view of the user's preference; and causing the at least one chromosome to evolve using a genetic algorithm, thereby obtaining control characteristics suitable to the user. In this method, the characteristics of the product can effectively be adjusted after its purchase based on the user's preference.

[ What is claimed is:] [1.]1. A method for real-time evolutionary control of an machine operated by a users, adaptive to the user based on the user's preference inferred from the user's operation of the machine, said machine being controlled by a control system, said control system outputting control signals for controlling the machine when receiving input signals, the relationship between the control signals and the input signals being defined by coefficients, said method comprising the steps of:(a) selecting plural sets of values of coefficients to create plural potential control units in the control system;(b) controlling the machine by using the control system with each potential control unit to evaluate control characteristics of each potential control unit;(c) inferring the user's preference for control characteristics from changes in the user's operation of the machine;(d) selecting at least one potential control unit based on the user's preference for its control characteristics;(e) subjecting said at least one potential control unit to evolutionary computing to create plural offspring potential control units, wherein each set of coefficient values are used as genes, each potential control unit is created as a chromosome, control characteristics expressed by each chromosome constitute an individual, and selection of individuals is conducted based on the user's preference; and(f) repeating steps (b) to (e) until the control system obtains control characteristics adapted to the user.
