MAYBE
The TRS could not be proven terminating. The proof attempt took 295 ms.
Problem 1 remains open; application of the following processors failed [DependencyGraph (5ms), SubtermCriterion (1ms), DependencyGraph (1ms), PolynomialLinearRange4iUR (74ms), DependencyGraph (1ms), PolynomialLinearRange8NegiUR (37ms), DependencyGraph (1ms), ReductionPairSAT (18ms), DependencyGraph (2ms), SizeChangePrinciple (8ms)].
from#(X) | → | from#(s(X)) |
2nd(cons(X, cons(Y, Z))) | → | Y | from(X) | → | cons(X, from(s(X))) |
Termination of terms over the following signature is verified: 2nd, s, from, cons
