MAYBE
The TRS could not be proven terminating. The proof attempt took 1361 ms.
Problem 1 remains open; application of the following processors failed [DependencyGraph (7ms), SubtermCriterion (1ms), DependencyGraph (10ms), PolynomialLinearRange4iUR (157ms), DependencyGraph (1ms), PolynomialLinearRange8NegiUR (726ms), DependencyGraph (1ms), ReductionPairSAT (275ms), DependencyGraph (1ms), SizeChangePrinciple (11ms)].
h#(f(x, y)) | → | h#(h(y)) | h#(f(x, y)) | → | h#(y) |
h(f(x, y)) | → | f(f(a, h(h(y))), x) |
Termination of terms over the following signature is verified: f, a, h
