MAYBE

'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  ge(x, 0()) -> true()
     , ge(0(), s(x)) -> false()
     , ge(s(x), s(y)) -> ge(x, y)
     , minus(x, 0()) -> x
     , minus(s(x), s(y)) -> minus(x, y)
     , div(x, y) -> ify(ge(y, s(0())), x, y)
     , ify(false(), x, y) -> divByZeroError()
     , ify(true(), x, y) -> if(ge(x, y), x, y)
     , if(false(), x, y) -> 0()
     , if(true(), x, y) -> s(div(minus(x, y), y))}

Proof Output:    
  The input cannot be shown compatible
