    Model: /media/gia/Data/Example-Models/Pipeline-KP12-2-5/Pipeline-KP12-2-5.imi
    Mode: EF-synthesis.
    Exploration order: layer-based BFS.
    Considering fixpoint variant with bidirectional inclusion of symbolic zones (instead of equality).
    Counterexample mode: the analysis will stop as soon as a target state is found.
    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 {a, e, c}
    - upper-bound parameters {b, f, d}
    
    Abstract model built after 0.008 second.

      [AGsafe] Found a new state violating the property.
      [AGsafe] Target state found! Terminating…
    
    Fixpoint reached at a depth of 15: 836 states with 923 transitions in the final state space.
    
      [AGsafe] Algorithm completed after 4.836 seconds.
    
    Final constraint such that the system is correct:
     a > b
    & b >= 0
    & c >= 0
    & d >= 0
    & e >= 0
    & f >= 0
    OR
      b >= a
    & a >= 0
    & 3*c + 10*e > d
    & c >= 0
    & d >= 0
    & e >= 0
    & f >= 0
    OR
      a >= 0
    & b >= a
    & c >= 0
    & d >= 3*c + 10*e
    & e > f
    & f >= 0
    OR
      b >= a
    & d >= 3*c + 10*e
    & c >= 0
    & f >= e
    & e >= 0
    & a + 2*c > d
    OR
      c + 9*e > b
    & a >= 0
    & b >= a
    & c >= 0
    & d >= 3*c + 10*e
    & e >= 0
    & f >= e
    This good constraint is an over-approximation of the actual result (or the actual result itself)
