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 1 terminating modules (1 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.1 modules have a trivial ranking function, the largest among these consists of 3 locations. The remainder module has 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.4s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. Highest rank in rank-based complementation 0. Minimization of det autom 1. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 5 states and ocurred in iteration 1. Nontrivial modules had stage [0, 0, 0, 0, 0].
