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 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.3s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 3.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 19 states and ocurred in iteration 2. Nontrivial modules had stage [2, 0, 0, 0, 0].
