Combs method

The Combs method is a rule base reduction method of writing fuzzy logic rules described by William E. Combs in 1997. It is designed to prevent combinatorial explosion in fuzzy logic rules.^[1]

The Combs method takes advantage of the logical equality $((p\land q)\Rightarrow r)\iff ((p\Rightarrow r)\lor (q\Rightarrow r))$ .
