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) , times(0(), y) -> 0() , times(s(x), y) -> plus(y, times(x, y)) , plus(0(), y) -> y , plus(s(x), y) -> s(plus(x, y)) , fac(x) -> loop(x, s(0()), s(0())) , loop(x, c, y) -> if(lt(x, c), x, c, y) , if(false(), x, c, y) -> loop(x, s(c), times(y, s(c))) , if(true(), x, c, y) -> y} Proof Output: The input cannot be shown compatible
