Abstract
A truth-valued-flow inference unit according to the invention is for outputting truth values representing inferential results regarding a plurality of antecedents for which consequents in implications are the same. The inference unit includes a selector circuit (18, 71-74, 81-84, 91-94, 75, 76, 85, 86, 95, 96) for selectively outputting, for each of a plurality of antecedents in accordance with set rules and with regard to each of a plurality of kinds of input variables, truth values inputted thereto in correspondence with respective ones of the input variables with regard to a plurality kinds of predetermined functions used by the antecedents, and an operation circuit (19, 77-80, 90) for performing an operation between the truth values outputted by the selector circuit and all input variables for each antecedent, and further for performing a unifying operation on the results of this operation.
