No generalized rewrite rule found! ## Applying the DP framework... ## Round 1: ## DP problem: Dependency pairs = [log^#(s(s(_0))) -> log^#(s(half(_0)))] TRS = {half(0) -> 0, half(s(s(_0))) -> s(half(_0)), log(s(0)) -> 0, log(s(s(_0))) -> s(log(s(half(_0))))} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {half(_0):[_0], s(_0):[2 * _0], 0:[1], log(_0):[_0], log^#(_0):[_0]} for all instantiations of the variables with values greater than or equal to mu = 1. This DP problem is finite. ## DP problem: Dependency pairs = [half^#(s(s(_0))) -> half^#(_0)] TRS = {half(0) -> 0, half(s(s(_0))) -> s(half(_0)), log(s(0)) -> 0, log(s(s(_0))) -> s(log(s(half(_0))))} ## Trying with homeomorphic embeddings... Success! 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
