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