One deterministic module has affine ranking function -2 * blastFlag + 1 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 735 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.8s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 2.8s. Construction of modules took 0.2s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 0. Minimization of nondet autom 4. Automata minimization 0.1s AutomataMinimizationTime, 4 MinimizatonAttempts, 131 StatesRemovedByMinimization, 3 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].
