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 1 terminating modules (0 trivial, 1 deterministic, 0 nondeterministic) and one module whose termination is unknown.One deterministic module has affine ranking function -1 * y + 10049 and consists of 5 locations. The remainder module has 22 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.5s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 17.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 0. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 3 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 22 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
