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. 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. Memory for abstract model: 871.164 KiB (i.e., 223018 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: 306 states with 366 transitions in the final state space. Exiting explore_queue_bfs!!!  [AGsafe] Algorithm completed after 0.317 second.  Final constraint such that the system is correct:  8*delta >= Delta & Delta >= 0 This good constraint is an over-approximation of the actual result (or the actual result itself) 9.226 MiB (i.e., 1209400 words of size 8)  Result written to file '/media/gia/Data/Example-Models/F4/F4-queueBFSPRIOR-incl-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 306 Number of transitions : 366 Number of computed states : 367 Total computation time : 0.311 second States/second in state space : 983.2 (306/0.311 second) Computed states/second : 1179.2 (367/0.311 second) Estimated memory : 9.328 MiB (i.e., 1222691 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/F4/F4-queueBFSPRIOR-incl-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/F4/F4-queueBFSPRIOR-incl-counterexample-statespace.states'…  Drawing the cartography… Plot cartography in 2D projected on parameters delta and Delta to file '/media/gia/Data/Example-Models/F4/F4-queueBFSPRIOR-incl-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.315 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.003 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 709 number of constraints comparisons : 452 number of new states <= old : 61 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 : 3.813 seconds cartography drawing : 0.051 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 4.183 seconds IMITATOR successfully terminated (after 4.186 seconds) Estimated memory used: 41.622 MiB (i.e., 5455558 words of size 8)
