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 6 terminating modules (3 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + -1 * nondetString1 + unknown-#length-unknown[nondetString1] and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[nondetString2] + -1 * nondetString2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s1 + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.1s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 7.2s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 6. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 2 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 19 states and ocurred in iteration 2. Nontrivial modules had stage [3, 0, 0, 0, 0].
