ABSTRACT:
In a computer system having a storage unit for storing at least one of a program and knowledge used for solving a problem, an input/output unit for inputting a problem to be presently solved, and an execution unit for obtaining a proposed solution of one of the problem to be presently solved and a partial problem of the problem, by using at least one of the program and knowledge in the storage unit, an inference processing method includes the steps of storing a modification case generated upon modification of a solution, calculating a portion, unable to be solved by the proposed solution obtained by the execution unit, of one of the problem to be solved and the partial problem, searching for a modification case containing a problem similar to the unsolved portion, from the modification cases generated upon modification of solutions to problems, correlating the searched modification case with the proposed solution obtained by the execution unit, and modifying the proposed solution obtained by the execution unit in accordance with the correlation and using the modified result as one of an overall solution and an intermediate solution of the problem to be solved presently.
