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 24 terminating modules (24 trivial, 0 deterministic, 0 nondeterministic). 24 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 29.4s and 25 iterations. TraceHistogramMax:5. Analysis of lassos took 20.9s. Construction of modules took 5.1s. Büchi inclusion checks took 3.2s. Highest rank in rank-based complementation 0. Minimization of det autom 24. Minimization of nondet autom 0. Automata minimization 0.3s AutomataMinimizationTime, 23 MinimizatonAttempts, 9186 StatesRemovedByMinimization, 23 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [0, 0, 0, 0, 0].
