One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function 7 + -2 * splverifierCounter and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.2s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 2.2s. Construction of modules took 0.0s. Büchi inclusion checks took 1.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 844 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 447 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
