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 = [f^#(g(_0),b) -> f^#(a,_0)] TRS = {a -> g(c), g(a) -> b, f(g(_0),b) -> f(a,_0)} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {a:[1], b:[1], c:[0], g(_0):[2 * _0], f(_0,_1):[_0 + _1], f^#(_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. ** 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 = 7
