Exploration order: layer-based BFS. 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: 945.710 KiB (i.e., 242102 words)  Starting running algorithm AGsafe…  Computing post^1 from 1 state.  [AGsafe] Found a new state violating the property.  [AGsafe] Target state found! Terminating…  Fixpoint reached at a depth of 2: 4 states with 3 transitions in the final state space.  [AGsafe] Algorithm completed after 0.020 second.  Final constraint such that the system is correct: False This good constraint is an over-approximation of the actual result (or the actual result itself) 2.027 MiB (i.e., 265766 words of size 8)  Result written to file '/media/gia/Data/Example-Models/FDDI/FDDI-layerBFS-incl-merge-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 4 Number of transitions : 3 Number of computed states : 4 Total computation time : 0.013 second States/second in state space : 295.8 (4/0.013 second) Computed states/second : 295.8 (4/0.013 second) Estimated memory : 2.127 MiB (i.e., 278828 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/FDDI/FDDI-layerBFS-incl-merge-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/FDDI/FDDI-layerBFS-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/FDDI/FDDI-layerBFS-incl-merge-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.018 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.004 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 0 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 : 0.061 second cartography drawing : 0.014 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 0.096 second IMITATOR successfully terminated (after 0.098 second) Estimated memory used: 2.336 MiB (i.e., 306290 words of size 8)
