Max. memory is 16.1GB. * 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 19 + -2 * i2 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.5s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 5.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 2 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 113 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
