Exploration order: queue-based BFS with ranking system [WORK IN PROGRESS]. Considering fixpoint variant with monodirectional 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.  Abstract model built after 0.008 second. Memory for abstract model: 1084.718 KiB (i.e., 277688 words)  Starting running algorithm AGsafe…  Entering explore_queue_bfs!!!  [AGsafe] Found a new state violating the property.  [AGsafe] Target state found! Terminating… End of Ordering!!!   Fixpoint reached: 45 states with 57 transitions in the final state space. Exiting explore_queue_bfs!!!  [AGsafe] Algorithm completed after 0.053 second.  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) 3.613 MiB (i.e., 473685 words of size 8)  Result written to file '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSRS-incl-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 45 Number of transitions : 57 Number of computed states : 58 Total computation time : 0.044 second States/second in state space : 1006.6 (45/0.044 second) Computed states/second : 1297.5 (58/0.044 second) Estimated memory : 3.717 MiB (i.e., 487209 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSRS-incl-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSRS-incl-counterexample-statespace.states'…  Drawing the cartography… Plot cartography in 2D projected on parameters A and B to file '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSRS-incl-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.051 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.006 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 22 number of constraints comparisons : 17 number of new states <= old : 13 number of new states >= old : 0 StateSpace.merging attempts : 0 StateSpace.merges : 0 StatesMerging.merging attempts : 0 StatesMerging.merges : 0 ------------------------------------------------------------ Statistics: Graphics-related counters ------------------------------------------------------------ state space drawing : 0.491 second cartography drawing : 0.034 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 0.580 second IMITATOR successfully terminated (after 0.583 second) Estimated memory used: 5.248 MiB (i.e., 687917 words of size 8)
