One deterministic module has affine ranking function unknown-#length-unknown[in] + -1 * i and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[in] + -1 * s and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 17 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.7s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 11.9s. Construction of modules took 0.1s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 2 StatesRemovedByMinimization, 2 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].
