MAYBE
The TRS could not be proven terminating. The proof attempt took 538 ms.
The following DP Processors were used
Problem 1 was processed with processor DependencyGraph (0ms).
| – Problem 2 remains open; application of the following processors failed [SubtermCriterion (1ms), DependencyGraph (1ms), PolynomialLinearRange4iUR (93ms), DependencyGraph (1ms), PolynomialLinearRange8NegiUR (180ms), DependencyGraph (2ms), ReductionPairSAT (153ms), DependencyGraph (1ms), SizeChangePrinciple (7ms)].
| – Problem 3 was processed with processor SubtermCriterion (0ms).
The following open problems remain:
Open Dependency Pair Problem 2
Dependency Pairs

Rewrite Rules
| f(s(0), g(x)) | → | f(x, g(x)) | | g(s(x)) | → | g(x) |
Original Signature
Termination of terms over the following signature is verified: f, g, 0, s
