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 = [c^#(b(a(_0))) -> c^#(c(_0)), c^#(b(a(_0))) -> c^#(_0)] TRS = {c(b(a(_0))) -> a(a(b(b(c(c(_0)))))), a(_0) -> e, b(_0) -> e, c(_0) -> e} ## 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 = [c^#(b(a(_0))) -> c^#(c(_0)), c^#(b(a(_0))) -> c^#(_0)] TRS = {c(b(a(_0))) -> a(a(b(b(c(c(_0)))))), a(_0) -> e, b(_0) -> e, c(_0) -> e} 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 = 235
