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. 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: 871.156 KiB (i.e., 223016 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 0.371 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) 14.428 MiB (i.e., 1891226 words of size 8)  Result written to file '/media/gia/Data/Example-Models/F4/F4-queueBFSRS-incl-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 306 Number of transitions : 366 Number of computed states : 367 Total computation time : 0.364 second States/second in state space : 838.4 (306/0.364 second) Computed states/second : 1005.5 (367/0.364 second) Estimated memory : 14.530 MiB (i.e., 1904497 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/F4/F4-queueBFSRS-incl-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/F4/F4-queueBFSRS-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-queueBFSRS-incl-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.369 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.003 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 698 number of constraints comparisons : 446 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 : 4.332 seconds cartography drawing : 0.036 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 4.755 seconds IMITATOR successfully terminated (after 4.758 seconds) Estimated memory used: 46.826 MiB (i.e., 6137622 words of size 8)
