One deterministic module has affine ranking function unknown-#length-unknown[s] + -1 * s and consists of 3 locations. One deterministic module has affine ranking function -1 * source + unknown-#length-unknown[source] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.1s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 5.3s. Construction of modules took 0.1s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 4 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].
