Free memory was 967.1 MB in the beginning and 966.1 MB in the end (delta: 1.1 MB). Peak memory consumption was 2.1 MB. Max. memory is 16.1 GB. * 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 23.8s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 7.9s. Construction of modules took 7.8s. Büchi inclusion checks took 4.8s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 1.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 41202 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 1.4s Buchi closure took 0.1s. Biggest automaton had 15343 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
