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 = [p^#(p(b(a(_0)),_1),p(_2,_3)) -> p^#(p(_3,a(_2)),p(b(a(_1)),b(_0)))] TRS = {p(p(b(a(_0)),_1),p(_2,_3)) -> p(p(_3,a(_2)),p(b(a(_1)),b(_0)))} ## Trying with homeomorphic embeddings... Failed! ## Trying with polynomial interpretations... Failed! ## 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 = [p^#(p(b(a(_0)),_1),p(_2,_3)) -> p^#(p(_3,a(_2)),p(b(a(_1)),b(_0)))] TRS = {p(p(b(a(_0)),_1),p(_2,_3)) -> p(p(_3,a(_2)),p(b(a(_1)),b(_0)))} Hence, could not prove (non)termination of the TRS under analysis.
