Peak memory consumption was 39.2MB. Max. memory is 16.1GB. * Witness Printer took 5.42ms. Allocated memory is still 417.3MB. Free memory is still 320.3MB. There was no memory consumed. Max. memory is 16.1GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 12 terminating modules (6 trivial, 6 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op6 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function 1 + -2 * op8 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. 6 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.0s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 8.8s. Construction of modules took 0.3s. Büchi inclusion checks took 4.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 10. Automata minimization 1.2s AutomataMinimizationTime, 10 MinimizatonAttempts, 17405 StatesRemovedByMinimization, 9 NontrivialMinimizations. Non-live state removal took 1.0s Buchi closure took 0.0s. Biggest automaton had 4434 states and ocurred in iteration 4. Nontrivial modules had stage [6, 0, 0, 0, 0].
