Analysis of Rule Refinement Conflicts
There exists no methodical standard for conflict analysis in the selection of optimal rule refinements. Current rule base refinement systems select the best rule refinements out o...

The Rule Retranslation Problem and the Validation Interface
Current rule base maintenance is wasting refinement and inference performance. There are only few maintenance concepts, which enjoy both (1) formal rule refinement and (2) utili...

On the design of metaheuristic algorithms using fuzzy rules
We present here a co-operative multithread metaheuristic. Each thread employs a (possibly) different optimization strategy and they are controlled by a Coordinator process. A rel...
