Exploration order: layer-based BFS. Considering fixpoint variant with bidirectional 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 {K} - upper-bound parameters {k}  Abstract model built after 0.006 second. Memory for abstract model: 881.804 KiB (i.e., 225742 words)  Starting running algorithm AGsafe…  Computing post^1 from 1 state. Computing post^2 from 3 states. Computing post^3 from 9 states. Computing post^4 from 15 states. Computing post^5 from 21 states. Computing post^6 from 36 states.  [AGsafe] Found a new state violating the property.  [AGsafe] Target state found! Terminating…  Fixpoint reached at a depth of 7: 88 states with 115 transitions in the final state space.  [AGsafe] Algorithm completed after 0.103 second.  Final constraint such that the system is correct:  k >= 0 & K >= k This good constraint is an over-approximation of the actual result (or the actual result itself) 4.017 MiB (i.e., 526639 words of size 8)  Result written to file '/media/gia/Data/Example-Models/fischer3/fischer3-layerBFS-incl2-counterexample.res'.  ------------------------------------------------------------ Statistics: State space ------------------------------------------------------------ Number of states : 88 Number of transitions : 115 Number of computed states : 116 Total computation time : 0.097 second States/second in state space : 903.9 (88/0.097 second) Computed states/second : 1191.5 (116/0.097 second) Estimated memory : 4.119 MiB (i.e., 539969 words of size 8)  Generating graphical output to '/media/gia/Data/Example-Models/fischer3/fischer3-layerBFS-incl2-counterexample-statespace.jpg'… Writing the states description to file '/media/gia/Data/Example-Models/fischer3/fischer3-layerBFS-incl2-counterexample-statespace.states'…  Drawing the cartography… Plot cartography in 2D projected on parameters k and K to file '/media/gia/Data/Example-Models/fischer3/fischer3-layerBFS-incl2-counterexample_cart.png'.  ------------------------------------------------------------ Statistics: Algorithm counters ------------------------------------------------------------ main algorithm : 0.101 second ------------------------------------------------------------ Statistics: Parsing counters ------------------------------------------------------------ model parsing : 0.003 second ------------------------------------------------------------ Statistics: State computation counters ------------------------------------------------------------ number of state comparisons : 318 number of constraints comparisons : 170 number of new states <= old : 28 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 : 0.429 second cartography drawing : 0.045 second ------------------------------------------------------------ Statistics: Global counter ------------------------------------------------------------ total : 0.580 second IMITATOR successfully terminated (after 0.583 second) Estimated memory used: 7.056 MiB (i.e., 924880 words of size 8)
