Allocated memory was 809.5MB in the beginning and 2.1GB in the end (delta: 1.3GB). Free memory was 475.9MB in the beginning and 979.7MB in the end (delta: -503.9MB). Peak memory consumption was 1.2GB. Max. memory is 16.1GB. * Witness Printer took 3.07ms. Allocated memory is still 2.1GB. Free memory is still 979.7MB. 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 3 terminating modules (2 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 26.1s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 7.8s. Construction of modules took 5.8s. Büchi inclusion checks took 11.7s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 1.1s AutomataMinimizationTime, 1 MinimizatonAttempts, 158910 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 1.5s Buchi closure took 0.1s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [1, 0, 0, 0, 0].
