One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function (N + ((long) -1 * k)) and consists of 4 locations. One deterministic module has affine ranking function (((long) -1 * j) + m) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 6 locations. One deterministic module has affine ranking function (N + ((long) -1 * k)) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -1 * j) + m) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.5s and 9 iterations. TraceHistogramMax:2. Analysis of lassos took 3.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 9. Automata minimization 0.0s AutomataMinimizationTime, 9 MinimizatonAttempts, 58 StatesRemovedByMinimization, 7 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 [5, 1, 1, 0, 0].
