MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          add(0(),x) -> x
          add(s(x),y) -> s(add(x,y))
          p(0(),s(x),y,z) -> q(x,add(x,z))
          p(s(x),y,z,u) -> p(x,s(y),s(s(z)),u)
          q(s(x),y) -> p(s(x),0(),s(0()),y)
      - Signature:
          {add/2,p/4,q/2} / {0/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {add,p,q} and constructors {0,s}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
