Failed! ## Trying with polynomial interpretations... Too many coefficients (15)! Aborting! ## Trying with lexicographic path orders... The constraints are satisfied by the lexicographic path order using the precedence: f > [g, s, +], g > [s, +], + > [s], 0 > [1] and the argument filtering: {f:[0], s:[0], g:[0, 1], +:[0, 1], g^#:[0, 1]} This DP problem is finite. ## DP problem: Dependency pairs = [+^#(_0,s(_1)) -> +^#(_0,_1)] TRS = {f(0) -> 1, f(s(_0)) -> g(_0,s(_0)), g(0,_0) -> _0, g(s(_0),_1) -> g(_0,+(_1,s(_0))), +(_0,0) -> _0, +(_0,s(_1)) -> s(+(_0,_1)), g(s(_0),_1) -> g(_0,s(+(_1,_0)))} ## Trying with homeomorphic embeddings... Success!
