Peak memory consumption was 76.8MB. Max. memory is 16.1GB. * Witness Printer took 4.15ms. Allocated memory is still 272.6MB. Free memory is still 125.3MB. 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 4 terminating modules (2 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[in] + -1 * i and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[in] + -1 * s and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 17 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.2s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 13.2s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 2 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [2, 0, 0, 0, 0].
