Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  plus(x, 0()) -> x
     , plus(x, s(y)) -> s(plus(x, y))
     , d(0()) -> 0()
     , d(s(x)) -> s(s(d(x)))
     , q(0()) -> 0()
     , q(s(x)) -> s(plus(q(x), d(x)))}

Proof Output:    
  The input cannot be shown compatible
