One deterministic module has affine ranking function -1 * i + hi and consists of 4 locations. One deterministic module has affine ranking function -1 * i + hi and consists of 4 locations. One deterministic module has affine ranking function -1 * i + N and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.7s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 3.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 0.2s AutomataMinimizationTime, 2 MinimizatonAttempts, 727 StatesRemovedByMinimization, 2 NontrivialMinimizations.
