MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { -(x, 0()) -> x , -(s(x), s(y)) -> -(x, y) , p(s(x)) -> x , f(s(x), y) -> f(p(-(s(x), y)), p(-(y, s(x)))) , f(x, s(y)) -> f(p(-(x, s(y))), p(-(s(y), x)))} Proof Output: The input cannot be shown compatible
