One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString] and consists of 5 locations. One deterministic module has affine ranking function -1 * from + unknown-#length-unknown[nondetString] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.4s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 5.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 10.4ms AutomataMinimizationTime, 2 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 12 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
