Exploration order: queue-based BFS with priority [WORK IN PROGRESS]. Considering fixpoint variant with monodirectional inclusion of symbolic zones (instead of equality). 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 0.009 second. Memory for abstract model: 1084.578 KiB (i.e., 277652 words)  Starting running algorithm AGsafe…  Entering explore_queue_bfs!!!  [AGsafe] Found a new state violating the property. End of Ordering!!!   State space exploration stopped: 1676 states with 3566 transitions in the final state space. Exiting explore_queue_bfs!!!  [AGsafe] Algorithm completed after 900.946 seconds.  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) 7.614 GiB (i.e., 1021991141 words of size 8)  Result written to file '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSPRIOR-incl-merge-EF.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 1676 Number of transitions : 3566 Number of computed states : 3567 Total computation time : 900.936 seconds States/second in state space : 1.8 (1676/900.936 seconds) Computed states/second : 3.9 (3567/900.936 seconds) Estimated memory : 7.614 GiB (i.e., 1022004728 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSPRIOR-incl-merge-EF-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/critical-region4/critical-region4-queueBFSPRIOR-incl-merge-EF-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-queueBFSPRIOR-incl-merge-EF_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 900.944 seconds ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.006 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 244241 number of constraints comparisons : 244205 number of new states <= old : 1891 number of new states >= old : 0 StateSpace.merging attempts : 40110712 StateSpace.merges : 0 StatesMerging.merging attempts : 0 StatesMerging.merges : 0 ------------------------------------------------------------ Statistics: Graphics-related counters ------------------------------------------------------------ state space drawing : 162.423 seconds cartography drawing : 0.051 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 1063.426 seconds IMITATOR successfully terminated (after 1063.428 seconds) Estimated memory used: 8.548 GiB (i.e., 1147360665 words of size 8)
