PROBLEM TO BE SOLVED: To optimize an algorithm adopting feedback in an evolutionary computation system for performing evolutionary computation by genetic programming. SOLUTION: Individual structure is defined in a network type, and in fitness calculation of each individual of an evolutionary computation process, periodical processing is repeated for inputting calculation result data of a different node or an own-node calculated in the preceding period in the calculation of each node to obtain an calculation result according to a network structure. Then, calculation result data obtained from a prescribed output node is compared with target data to calculate fitness in the last period. COPYRIGHT: (C)2008,JPO&INPIT
