One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[nondetString1] and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.9s and 3 iterations. TraceHistogramMax:2. Analysis of lassos took 4.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 19 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
