Free memory was 150.1MB in the beginning and 176.6MB in the end (delta: -26.4MB). Peak memory consumption was 70.1MB. Max. memory is 16.1GB. * Witness Printer took 2.30ms. Allocated memory is still 327.2MB. Free memory was 176.6MB in the beginning and 175.5MB in the end (delta: 1.1MB). Peak memory consumption was 2.1MB. 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 4.6s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 2.9s. Construction of modules took 0.0s. Büchi inclusion checks took 1.2s. 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 0.1s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [3, 0, 0, 0, 0].
