    Model: /media/gia/Data/Example-Models/F4/F4.imi
    Mode: EF-synthesis.
    Exploration order: layer-based BFS.
    Considering fixpoint variant with monodirectional inclusion of symbolic zones (instead of equality).
    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 an L/U-PTA:
    - lower-bound parameters {delta}
    - upper-bound parameters {Delta}
    
    Abstract model built after 0.006 second.
