One deterministic module has affine ranking function N + -1 * i and consists of 3 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[numbers][k * 4 + -4 + numbers] and consists of 8 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[a][i * 4 + a] and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[a][a + i * 4] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.5s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 7.4s. Construction of modules took 0.1s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 4. Automata minimization 12.2ms AutomataMinimizationTime, 6 MinimizatonAttempts, 16 StatesRemovedByMinimization, 5 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 22 states and ocurred in iteration 4. Nontrivial modules had stage [4, 0, 1, 0, 0].
