'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  f(0(), n) -> g(0(), n)
     , f(m, 0()) -> g(m, 0())
     , f(s(m), s(n)) -> h(m, n, f(m, p(m, n)), f(s(m), n))
     , g(n, m) -> bot()
     , p(m, n) -> bot()
     , h(k, l, m, n) -> bot()}

Proof Output:    
  The input cannot be shown compatible
