No generalized rewrite rule found! ## Applying the DP framework... ## Round 1: ## DP problem: Dependency pairs = [+^#(s(_0),s(_1)) -> +^#(s(_0),+(_1,0))] TRS = {+(0,_0) -> _0, +(s(_0),0) -> s(_0), +(s(_0),s(_1)) -> s(+(s(_0),+(_1,0)))} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {+(_0,_1):[_0 * _1], 0:[1], s(_0):[2 * _0], +^#(_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 = 11
