One deterministic module has affine ranking function -2 * op1 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op2 + 1 and consists of 4 locations. One deterministic module has affine ranking function 5 + -2 * splverifierCounter and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.9s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 2.5s. Construction of modules took 0.3s. Büchi inclusion checks took 6.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 108.5ms AutomataMinimizationTime, 4 MinimizatonAttempts, 1392 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 1.0s Buchi closure took 0.0s. Biggest automaton had 1039 states and ocurred in iteration 2. Nontrivial modules had stage [3, 0, 0, 0, 0].
