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