    + Applied Processor:
        ArgumentFilter [2,3,4,5,6,7]

        We remove following argument positions: [2,3,4,5,6,7].

    + Applied Processor:
        UnsatPaths
    + Details:
        We remove following edges from the transition graph: [(2,1),(2,3),(3,1),(3,2)]
* Step 3: FromIts MAYBE

    + Details:
        ()
* Step 5: Failure MAYBE
  + Considered Problem:
      Rules:
        f2(A,B)   -> f1(A,B)         True
        f1(A,B)   -> f300(A,A)       [A = B]

  + Applied Processor:
      Decompose Greedy
  + Details:
      We construct a looptree:
