TIMEOUT
The TRS could not be proven terminating. The proof attempt took 60000 ms.
The following DP Processors were used
Problem 1 was processed with processor DependencyGraph (9ms).
| – Problem 2 remains open; application of the following processors failed [SubtermCriterion (1ms), DependencyGraph (1ms), PolynomialLinearRange4iUR (65ms), DependencyGraph (1ms), PolynomialLinearRange8NegiUR (49ms), DependencyGraph (2ms), ReductionPairSAT (150ms), DependencyGraph (1ms), SizeChangePrinciple (4ms), ForwardNarrowing (1ms), BackwardInstantiation (1ms), ForwardInstantiation (1ms), Propagation (1ms)].
The following open problems remain:
