'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  minus(x, x) -> 0()
     , minus(x, y) -> cond(equal(min(x, y), y), x, y)
     , cond(true(), x, y) -> s(minus(x, s(y)))
     , min(0(), v) -> 0()
     , min(u, 0()) -> 0()
     , min(s(u), s(v)) -> s(min(u, v))
     , equal(0(), 0()) -> true()
     , equal(s(x), 0()) -> false()
     , equal(0(), s(y)) -> false()
     , equal(s(x), s(y)) -> equal(x, y)}

Proof Output:    
  The input cannot be shown compatible
