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, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[__builtin_alloca (n * sizeof(char))] and consists of 5 locations. One deterministic module has affine ranking function 3 + -2 * p and consists of 9 locations. One deterministic module has affine ranking function -1 * p + unknown-#length-unknown[p] and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.9s and 6 iterations. TraceHistogramMax:3. Analysis of lassos took 10.5s. Construction of modules took 0.1s. Büchi inclusion checks took 1.0s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 5 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, 0, 0, 0].
