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 (2 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function 7 + -2 * splverifierCounter and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.9s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 2.7s. Construction of modules took 0.0s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 2. Automata minimization 0.1s AutomataMinimizationTime, 2 MinimizatonAttempts, 1032 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 541 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
