No generalized rewrite rule found! ## Applying the DP framework... ## Round 1: ## DP problem: Dependency pairs = [g^#(f(_0,_1),_2) -> g^#(_1,_2), g^#(h(_0,_1),_2) -> g^#(_0,f(_1,_2)), g^#(_0,h(_1,_2)) -> g^#(_0,_1)] TRS = {g(f(_0,_1),_2) -> f(_0,g(_1,_2)), g(h(_0,_1),_2) -> g(_0,f(_1,_2)), g(_0,h(_1,_2)) -> h(g(_0,_1),_2)} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... Too many coefficients (13)! Aborting! ## Trying with lexicographic path orders... The constraints are satisfied by the lexicographic path order using the precedence: g > [h, f] and the argument filtering: {g:[0, 1], h:[0, 1], f:[0, 1], g^#:[0, 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 = 20
