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 5 terminating modules (3 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + len and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + 8 * j and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.3s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 5.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 16 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 [2, 0, 0, 0, 0].
