-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  f(true(), x, y, z) -> f(gt(x, plus(y, z)), x, s(y), z)
     , f(true(), x, y, z) -> f(gt(x, plus(y, z)), x, y, s(z))
     , plus(n, 0()) -> n
     , plus(n, s(m)) -> s(plus(n, m))
     , gt(0(), v) -> false()
     , gt(s(u), 0()) -> true()
     , gt(s(u), s(v)) -> gt(u, v)}

Proof Output:    
  The input cannot be shown compatible
