Max. memory is 11.5 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 1 terminating modules (0 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function x and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.2s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 0.9s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 0. Automata minimization No data available. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 0 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
