Max. memory is 11.5 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 5 terminating modules (5 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.5 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 1197 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.9s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 7.6s. Construction of modules took 1.6s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 0. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 5 MinimizatonAttempts, 236 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 1197 states and ocurred in iteration 5. Nontrivial modules had stage [0, 0, 0, 0, 0].
