Max. memory is 16.1 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 4 terminating modules (3 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + cleanupTimeShifts and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 20.7s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.8s. Construction of modules took 0.9s. Büchi inclusion checks took 5.6s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 2.8s AutomataMinimizationTime, 2 MinimizatonAttempts, 206 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 1.8s Buchi closure took 0.1s. Biggest automaton had 49119 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
