One deterministic module has affine ranking function -1 * k + N and consists of 4 locations. One deterministic module has affine ranking function N + -1 * i and consists of 3 locations. One deterministic module has affine ranking function N + -1 * j and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.7s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 2.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 169 StatesRemovedByMinimization, 2 NontrivialMinimizations.
