One deterministic module has affine ranking function unknown-#memory_int-unknown[qq][qq] and consists of 8 locations. One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[op][op] + 1 and consists of 5 locations. One nondeterministic module has affine ranking function 3 + 2 * \old(unknown-#memory_int-unknown)[op][0] and consists of 7 locations. 2 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.6s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 11.6s. Construction of modules took 0.1s. Büchi inclusion checks took 1.6s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 22.1ms AutomataMinimizationTime, 4 MinimizatonAttempts, 18 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 83 states and ocurred in iteration 3. Nontrivial modules had stage [2, 0, 1, 0, 0].
