Exploration order: queue-based BFS with priority [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. 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.  Abstract model built after 0.007 second. Memory for abstract model: 890.632 KiB (i.e., 228002 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: 21 states with 23 transitions in the final state space. Exiting explore_queue_bfs!!!  [AGsafe] Algorithm completed after 0.023 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) 2.247 MiB (i.e., 294605 words of size 8)  Result written to file '/media/gia/Data/Example-Models/critical-region/critical-region-queueBFSPRIOR-incl-merge-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 21 Number of transitions : 23 Number of computed states : 24 Total computation time : 0.015 second States/second in state space : 1351.9 (21/0.015 second) Computed states/second : 1545.1 (24/0.015 second) Estimated memory : 2.351 MiB (i.e., 308201 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/critical-region/critical-region-queueBFSPRIOR-incl-merge-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/critical-region/critical-region-queueBFSPRIOR-incl-merge-counterexample-statespace.states'…  Drawing the cartography… Plot cartography in 2D projected on parameters A and B to file '/media/gia/Data/Example-Models/critical-region/critical-region-queueBFSPRIOR-incl-merge-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.021 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.003 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 8 number of constraints comparisons : 5 number of new states <= old : 3 number of new states >= old : 0 StateSpace.merging attempts : 10 StateSpace.merges : 0 StatesMerging.merging attempts : 0 StatesMerging.merges : 0 ------------------------------------------------------------ Statistics: Graphics-related counters ------------------------------------------------------------ state space drawing : 0.146 second cartography drawing : 0.037 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 0.208 second IMITATOR successfully terminated (after 0.211 second) Estimated memory used: 2.857 MiB (i.e., 374586 words of size 8)
