MAYBE
The TRS could not be proven terminating. The proof attempt took 343 ms.
Problem 1 remains open; application of the following processors failed [DependencyGraph (5ms), SubtermCriterion (1ms), DependencyGraph (2ms), PolynomialLinearRange4iUR (74ms), DependencyGraph (1ms), PolynomialLinearRange8NegiUR (71ms), DependencyGraph (1ms), ReductionPairSAT (64ms), DependencyGraph (1ms), SizeChangePrinciple (8ms)].
ap#(f, x) | → | ap#(f, app(g, x)) |
ap(ap(g, x), y) | → | y | ap(f, x) | → | ap(f, app(g, x)) |
Termination of terms over the following signature is verified: f, app, g, ap
