One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 4 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 5 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.3s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 5.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 18 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 22 states and ocurred in iteration 3. Nontrivial modules had stage [3, 0, 1, 0, 0].
