Allocated memory was 469.8MB in the beginning and 564.1MB in the end (delta: 94.4MB). Free memory was 117.5MB in the beginning and 143.4MB in the end (delta: -25.9MB). Peak memory consumption was 69.5MB. Max. memory is 16.1GB. * Witness Printer took 2.52ms. Allocated memory is still 564.1MB. Free memory is still 143.4MB. 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 4 terminating modules (3 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.8s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 10.2s. Construction of modules took 0.3s. Büchi inclusion checks took 2.7s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.3s AutomataMinimizationTime, 2 MinimizatonAttempts, 17122 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.2s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [1, 0, 0, 0, 0].
