Allocated memory was 184.5MB in the beginning and 285.2MB in the end (delta: 100.7MB). Free memory was 95.9MB in the beginning and 190.2MB in the end (delta: -94.2MB). Peak memory consumption was 5.4MB. Max. memory is 16.1GB. * Witness Printer took 2.08ms. Allocated memory is still 285.2MB. Free memory is still 190.2MB. 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 6 terminating modules (3 trivial, 3 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 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 5 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.1s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 2.6s. Construction of modules took 0.0s. Büchi inclusion checks took 1.0s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 0.1s AutomataMinimizationTime, 4 MinimizatonAttempts, 3191 StatesRemovedByMinimization, 4 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 1108 states and ocurred in iteration 2. Nontrivial modules had stage [3, 0, 0, 0, 0].
