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 (2 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(length1 * sizeof(char))] + -1 * sc1 and consists of 3 locations. One deterministic module has affine ranking function 2 * s + 1 and consists of 3 locations. One nondeterministic module has affine ranking function 2 * s + unknown-#length-unknown[s] and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.9s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 8.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 8 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 25 states and ocurred in iteration 4. Nontrivial modules had stage [2, 0, 1, 0, 0].
