YES Prover = TRS(tech=PATTERN_RULES, nb_unfoldings=unlimited, max_nb_unfolded_rules=200) ** BEGIN proof argument ** All the DP problems were proved finite. As all the involved DP processors are sound, the TRS under analysis terminates. ** END proof argument ** ** BEGIN proof description ** ## Searching for a generalized rewrite rule (a rule whose right-hand side contains a variable that does not occur in the left-hand side)... No generalized rewrite rule found! ## Applying the DP framework... ## Round 1: ## DP problem: Dependency pairs = [not^#(and(_0,_1)) -> not^#(_0), not^#(and(_0,_1)) -> not^#(_1), not^#(or(_0,_1)) -> not^#(_0), not^#(or(_0,_1)) -> not^#(_1)] TRS = {or(_0,_0) -> _0, and(_0,_0) -> _0, not(not(_0)) -> _0, not(and(_0,_1)) -> or(not(_0),not(_1)), not(or(_0,_1)) -> and(not(_0),not(_1))} ## Trying with homeomorphic embeddings... Success! This DP problem is finite. ** END proof description ** Proof stopped at iteration 0 Number of unfolded rules generated by this proof = 0 Number of unfolded rules generated by all the parallel proofs = 0
