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 2 terminating modules (0 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(length * sizeof(char))] + -1 * src and consists of 4 locations. One deterministic module has affine ranking function 2 * us + unknown-#length-unknown[__builtin_alloca(n * sizeof(char))] and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.2s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 4.9s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 10 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
