Filed: 1989-05-02
Abstract: PURPOSE:To attain the time limit termination of the retrieval processing of a solution candidate by disposing a storage means storing data including the solution candidate, a timer and a retrieving means and compulsorily terminating the retrieval processing of resolution candidate space when it does not terminate within the prescribed time. CONSTITUTION:An execution time limit value is set in the timer 10 when the retrieval processing starts, and a signal designating the solution candidate is supplied to the retrieving means 20. Then, the means 20 retrieves the content of a storage means 30 in which data including the solution candidate is stored based on the solution candi date designation signal. The value of the content of the timer 10 is reduced in accor dance with the lapse of time. When the value reaches a prescribed value, '0' for example, a processing termination signal is outputted. The means 10 terminates the retrieval processing when the processing termination signal is supplied, and outputs a retrieval state signal showing a retrieval result till then. Thus, the time limit of the retrieval processing of the solution candidate can be attained. For starting the subsequent retrieval processing, the solution candidate designation signal is generated from the retrieval state signal outputted last time and the execution time limit value is designated again, whereby the processing can be resumed.
