-----------------------------------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  a__and(tt(), X) -> mark(X)
     , a__plus(N, 0()) -> mark(N)
     , a__plus(N, s(M)) -> s(a__plus(mark(N), mark(M)))
     , mark(and(X1, X2)) -> a__and(mark(X1), X2)
     , mark(plus(X1, X2)) -> a__plus(mark(X1), mark(X2))
     , mark(tt()) -> tt()
     , mark(0()) -> 0()
     , mark(s(X)) -> s(mark(X))
     , a__and(X1, X2) -> and(X1, X2)
     , a__plus(X1, X2) -> plus(X1, X2)}
