To obtain the solution of high arrangement efficiency at high speed.
An initial population composed of the plural chromosomes of a prescribed form is generated (step 100), the fitness of the respective chromosomes is calculated (step 110), the chromosome is selected from the population by a probability corresponding to the fitness, a cross processing (step 120) is executed and a new chromosome is generated. When the discrepancy of the gene data of the new chromosome is present, correction is performed (step 130) and the processings of the steps 120 and 130 are repeated until the prescribed number of the new chromosomes are attained (step 140). Thereafter, a mutation processing is executed (step 160), the fitness of the respective chromosomes is calculated (step 160), and when prescribed fitness is obtained, a series of the processings are ended (step 170). On the other hand, in the case that the prescribed fitness is not obtained, the processings from the step 120 are repeated.
