* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          -(x,0()) -> x
          -(x,s(y)) -> if(greater(x,s(y)),s(-(x,p(s(y)))),0())
          -(0(),y) -> 0()
          p(0()) -> 0()
          p(s(x)) -> x
      - Signature:
          {-/2,p/1} / {0/0,greater/2,if/3,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {-,p} and constructors {0,greater,if,s}
