MAYBE

'Pop* with parameter subtitution (timeout of 60.0 seconds)'
-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  cond1(true(), x, y) -> cond2(gr(x, 0()), x, y)
     , cond2(true(), x, y) -> cond1(or(gr(x, 0()), gr(y, 0())), p(x), y)
     , cond2(false(), x, y) -> cond3(gr(y, 0()), x, y)
     , cond3(true(), x, y) -> cond1(or(gr(x, 0()), gr(y, 0())), x, p(y))
     , cond3(false(), x, y) -> cond1(or(gr(x, 0()), gr(y, 0())), x, y)
     , gr(0(), x) -> false()
     , gr(s(x), 0()) -> true()
     , gr(s(x), s(y)) -> gr(x, y)
     , or(false(), false()) -> false()
     , or(true(), x) -> true()
     , or(x, true()) -> true()
     , p(0()) -> 0()
     , p(s(x)) -> x}

Proof Output:    
  The input cannot be shown compatible
