One deterministic module has affine ranking function -1 * sc1 + unknown-#length-unknown[nondetString1] and consists of 3 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[nondetString2] and consists of 4 locations. One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[nondetString2] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.8s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 9.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 21 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, 1, 0, 0].
