One deterministic module has affine ranking function -1 * i + cleanupTimeShifts and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.9s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 4.5s. Construction of modules took 0.0s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization No data available. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 0 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
