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 (0 trivial, 4 deterministic, 2 nondeterministic). One deterministic module has affine ranking function i and consists of 9 locations. One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[p][p] + 1 and consists of 5 locations. One deterministic module has affine ranking function aux-rec(op)-aux + i and consists of 8 locations. One deterministic module has affine ranking function i and consists of 8 locations. One nondeterministic module has affine ranking function 2 * unknown-#memory_int-unknown[p][p] + 1 and consists of 6 locations. One nondeterministic module has affine ranking function aux-rec(op)-aux + i and consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.5s and 7 iterations. TraceHistogramMax:3. Analysis of lassos took 13.4s. Construction of modules took 0.4s. Büchi inclusion checks took 3.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 5. Automata minimization 0.1s AutomataMinimizationTime, 5 MinimizatonAttempts, 111 StatesRemovedByMinimization, 5 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 [4, 0, 2, 0, 0].
