One deterministic module has affine ranking function cleanupTimeShifts + -1 * i 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 7.7s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 5.6s. Construction of modules took 0.0s. Büchi inclusion checks took 1.3s. 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].
