Max. memory is 16.1 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 5 terminating modules (4 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -2 * i2 + 27 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 181.3s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 180.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
