PROBLEM TO BE SOLVED: To allow a simulation result of an unnecessary hypothesis to be easily deleted, and allow a memory area after the deletion to be efficiently reused.SOLUTION: A hypothesis evaluation processing unit 9 compares, when being given observation information at a certain simulation time, the observation information with simulation results of hypotheses at the simulation time that are stored in ring buffers 2 of a simulation result storage unit 1; specifies one of the hypotheses whose simulation result does not match the observation information; and resets one of the ring buffers 2 that stores the simulation result of the hypothesis. |
