* Step 1: ArgumentFilter WORST_CASE(?,O(1))
    + Considered Problem:
        Rules:
          0. f0(A,B,C,D,E) -> f28(4,0,1,2,3) True (1,1)
        Signature:
          {(f0,5);(f28,5)}
        Flow Graph:
          [0->{}]
        
    + Applied Processor:
        ArgumentFilter [0,1,2,3,4]
    + Details:
        The problem is already solved.
