-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  cond(true(), x, y) ->
       cond(and(gr(x, 0()), gr(y, 0())), p(x), p(y))
     , and(true(), true()) -> true()
     , and(x, false()) -> false()
     , and(false(), x) -> false()
     , gr(0(), 0()) -> false()
     , gr(0(), x) -> false()
     , gr(s(x), 0()) -> true()
     , gr(s(x), s(y)) -> gr(x, y)
     , p(0()) -> 0()
     , p(s(x)) -> x}

Proof Output:    
  The input cannot be shown compatible
