MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { U11(tt(), M, N) -> U12(tt(), M, N) , U12(tt(), M, N) -> s(plus(N, M)) , U21(tt(), M, N) -> U22(tt(), M, N) , U22(tt(), M, N) -> plus(x(N, M), N) , plus(N, 0()) -> N , plus(N, s(M)) -> U11(tt(), M, N) , x(N, 0()) -> 0() , x(N, s(M)) -> U21(tt(), M, N)} Proof Output: The input cannot be shown compatible
