    Model: /media/gia/Data/Example-Models/critical-region4/critical-region4.imi
    Mode: EF-synthesis.
    Exploration order: layer-based BFS.
    Considering fixpoint variant with bidirectional 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.

    Final constraint such that the system is correct:
     A >= 0
    & B >= 0
    & 1 > A
    This good constraint is an over-approximation of the actual result (or the actual result itself)
