    Model: /media/gia/Data/Example-Models/Sched2.50.2/Sched2.50.2.imi
    Mode: EF-synthesis.
    Exploration order: queue-based BFS with ranking system [WORK IN PROGRESS].
    Considering fixpoint variant with monodirectional inclusion of symbolic zones (instead of equality).
    Merging technique of [AFS13] enabled.
    The cartography will be drawn.
    The result will be written to a file.
    The trace set(s) will be generated in a graphical mode.
    Description of states will be output.
    This model is a U-PTA.

    End of Ordering!!! 
    
    
    Fixpoint reached: 449 states with 549 transitions in the final state space.
    Exiting explore_queue_bfs!!!
    
      [AGsafe] Algorithm completed after 224.552 seconds.
    
    Final constraint such that the system is correct:
     C3_WORST >= 20
    & b >= 10
    & 50 >= 2*b + C3_WORST
    This good constraint is exact (sound and complete)
