MAYBE
The TRS could not be proven terminating. The proof attempt took 1644 ms.
Problem 1 remains open; application of the following processors failed [DependencyGraph (10ms), SubtermCriterion (1ms), DependencyGraph (9ms), PolynomialLinearRange4iUR (143ms), DependencyGraph (2ms), PolynomialLinearRange8NegiUR (919ms), DependencyGraph (2ms), ReductionPairSAT (418ms), DependencyGraph (1ms), SizeChangePrinciple (18ms)].
f#(h(x), y) | → | f#(x, h(a)) | f#(h(x), y) | → | f#(y, f(x, h(a))) |
f(h(x), y) | → | h(f(y, f(x, h(a)))) |
Termination of terms over the following signature is verified: f, a, h
