One deterministic module has affine ranking function unknown-#memory_int-unknown[M][M] + -1 * unknown-#memory_int-unknown[i][i] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[N][N] + -1 * unknown-#memory_int-unknown[j][j] and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 28.7s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 17.9s. Construction of modules took 0.0s. Büchi inclusion checks took 10.5s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 12.9ms AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 11 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
