One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y_ref][y_ref] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 6 locations. 5 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.1s and 9 iterations. TraceHistogramMax:1. Analysis of lassos took 9.8s. Construction of modules took 0.1s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 6. Automata minimization 31.0ms AutomataMinimizationTime, 7 MinimizatonAttempts, 24 StatesRemovedByMinimization, 4 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 71 states and ocurred in iteration 7. Nontrivial modules had stage [3, 0, 0, 0, 0].
