<p>PURPOSE: To provide an optimum solution searching device capable of accelerating a processing speed and easily obtaining an optimum solution in a short time in a device utilizing genetic algorithm for obtaining the optimum solution from the combination of the plural pieces of information within one environmental condition. CONSTITUTION: This optimum solution searching device 1 for obtaining an information body provided with a solution optimum for the condition requested by an environment from an information body set S1 formed by the plural pieces of the information bodies (J1 -Jn ) is provided with a searching processing means 3 for executing a searching processing to the respective information bodies (J1 -Jn ) of the inputted information body set S1, an adaptivity value computing means 4 for computing the adaptivity values (f) of the solutions indicated by the respective information bodies (J1 -Jn ), a change rate computing means 9 for computing the change rateΔf/ΔG of the adaptivity values of the respective information bodies (J1 -Jn ) and an introduction information body selection means 14 for selecting an introduction information body group provided with the degree of deformation from an existing information body in the environment (searching space) when the change rateΔf/ΔG of the adaptivity value gets dull from the information body set for which a searching processing operation is performed at present.</p> |
