-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  times(x, y) -> help(x, y, 0())
     , help(x, y, c) -> if(lt(c, y), x, y, c)
     , if(true(), x, y, c) -> plus(x, help(x, y, s(c)))
     , if(false(), x, y, c) -> 0()
     , lt(0(), s(x)) -> true()
     , lt(s(x), 0()) -> false()
     , lt(s(x), s(y)) -> lt(x, y)
     , plus(x, 0()) -> x
     , plus(0(), x) -> x
     , plus(x, s(y)) -> s(plus(x, y))
     , plus(s(x), y) -> s(plus(x, y))}

Proof Output:    
  The input cannot be shown compatible
