No generalized rewrite rule found! ## Applying the DP framework... ## 1 initial DP problem to solve. ## First, we try to decompose this problem into smaller problems. ## Round 1 [1 DP problem]: ## DP problem: Dependency pairs = [h^#(g(_0)) -> h^#(f(_0))] TRS = {f(a) -> g(h(a)), h(g(_0)) -> g(h(f(_0))), k(_0,h(_0),a) -> h(_0), k(f(_0),_1,_0) -> f(_0)} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... This DP problem is too complex! Aborting! ## Trying with lexicographic path orders... Failed! ## Trying with Knuth-Bendix orders... Failed! Don't know whether this DP problem is finite. ## A DP problem could not be proved finite. ## Now, we try to prove that this problem is infinite. ## Could not solve the following DP problems: 1: Dependency pairs = [h^#(g(_0)) -> h^#(f(_0))] TRS = {f(a) -> g(h(a)), h(g(_0)) -> g(h(f(_0))), k(_0,h(_0),a) -> h(_0), k(f(_0),_1,_0) -> f(_0)} Hence, could not prove (non)termination of the TRS under analysis. Proof run on Linux version 3.10.0-1160.25.1.el7.x86_64 for amd64 using Java version 1.8.0_292 ** END proof description ** Total number of generated unfolded rules = 27 popout
