MAYBE
The TRS could not be proven terminating. The proof attempt took 319 ms.
Problem 1 remains open; application of the following processors failed [DependencyGraph (6ms), SubtermCriterion (1ms), DependencyGraph (1ms), PolynomialLinearRange4iUR (96ms), DependencyGraph (2ms), PolynomialLinearRange8NegiUR (36ms), DependencyGraph (1ms), ReductionPairSAT (22ms), DependencyGraph (2ms), SizeChangePrinciple (4ms)].
f#(a, X) | → | f#(X, X) |
f(a, X) | → | f(X, X) | c | → | a | |
c | → | b |
Termination of terms over the following signature is verified: f, b, c, a
