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 0.012 second. Memory for abstract model: 1198.664 KiB (i.e., 306858 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: 32 states with 31 transitions in the final state space. Exiting explore_queue_bfs!!!  [AGsafe] Algorithm completed after 0.096 second.  Final constraint such that the system is correct:  sa >= 0 & td > 0 OR 3*sa > 50 & td = 0 This good constraint is an over-approximation of the actual result (or the actual result itself) 3.515 MiB (i.e., 460824 words of size 8)  Result written to file '/media/gia/Data/Example-Models/FDDI4/FDDI4-queueBFSPRIOR-incl-merge-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 32 Number of transitions : 31 Number of computed states : 32 Total computation time : 0.080 second States/second in state space : 396.0 (32/0.080 second) Computed states/second : 396.0 (32/0.080 second) Estimated memory : 3.619 MiB (i.e., 474375 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/FDDI4/FDDI4-queueBFSPRIOR-incl-merge-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/FDDI4/FDDI4-queueBFSPRIOR-incl-merge-counterexample-statespace.states'…  Drawing the cartography… Plot cartography in 2D projected on parameters sa and td to file '/media/gia/Data/Example-Models/FDDI4/FDDI4-queueBFSPRIOR-incl-merge-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.094 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.012 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 6 number of constraints comparisons : 0 number of new states <= old : 0 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 : 0.254 second cartography drawing : 0.039 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 0.389 second IMITATOR successfully terminated (after 0.392 second) Estimated memory used: 4.991 MiB (i.e., 654192 words of size 8)
