No generalized rewrite rule found! ## Applying the DP framework... ## Round 1: ## DP problem: Dependency pairs = [+^#(_0,+(_1,_2)) -> +^#(+(_0,_1),_2), +^#(_0,+(_1,_2)) -> +^#(_0,_1)] TRS = {f(+(_0,0)) -> f(_0), +(_0,+(_1,_2)) -> +(+(_0,_1),_2)} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {0:[0], f(_0):[_0], +(_0,_1):[1 + _0 + _1], +^#(_0,_1):[_0]} for all instantiations of the variables with values greater than or equal to mu = 0. This DP problem is finite. ## DP problem: Dependency pairs = [f^#(+(_0,0)) -> f^#(_0)] TRS = {f(+(_0,0)) -> f(_0), +(_0,+(_1,_2)) -> +(+(_0,_1),_2)} ## Trying with homeomorphic embeddings... Success!
