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 7 terminating modules (3 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (((long) -2 * i) + 5) and consists of 5 locations. One deterministic module has affine ranking function (((long) -2 * i) + 9) and consists of 4 locations. One deterministic module has affine ranking function (((long) -2 * j) + 19) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -2 * j) + 19) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.7s and 8 iterations. TraceHistogramMax:11. Analysis of lassos took 2.7s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 5. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 26 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [3, 0, 1, 0, 0].
