MAYBE 'epo* (timeout of 60.0 seconds)' -------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { lt(0(), s(x)) -> true() , lt(x, 0()) -> false() , lt(s(x), s(y)) -> lt(x, y) , fac(x) -> help(x, 0()) , help(x, c) -> if(lt(c, x), x, c) , if(true(), x, c) -> times(s(c), help(x, s(c))) , if(false(), x, c) -> s(0())} Proof Output: The input cannot be shown compatible
