Max. memory is 11.5 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 3 terminating modules (2 trivial, 1 deterministic, 0 nondeterministic) and one module whose termination is unknown.One deterministic module has affine ranking function -1 * i + length and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 18 locations. The remainder module has 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.5s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 7.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 2 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 14 states and ocurred in iteration 3. Nontrivial modules had stage [1, 0, 0, 0, 0].
