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 = [implies^#(not(_0),not(_1)) -> implies^#(_1,and(_0,_1))] TRS = {and(_0,false) -> false, and(_0,not(false)) -> _0, not(not(_0)) -> _0, implies(false,_0) -> not(false), implies(_0,false) -> not(_0), implies(not(_0),not(_1)) -> implies(_1,and(_0,_1))} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {and(_0,_1):[_0 + _1], not(_0):[2 * _0], false:[1], implies(_0,_1):[2 * _0 + 2 * _1], implies^#(_0,_1):[_0 + _1]} for all instantiations of the variables with values greater than or equal to mu = 1. 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 = 507
