Free memory was 739.0 MB in the beginning and 1.5 GB in the end (delta: -781.1 MB). Peak memory consumption was 94.4 MB. Max. memory is 16.1 GB. * Witness Printer took 4.28 ms. Allocated memory is still 1.8 GB. Free memory is still 1.5 GB. There was no memory consumed. 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 4 terminating modules (3 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.8s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 4.9s. Construction of modules took 0.9s. Büchi inclusion checks took 2.3s. Highest rank in rank-based complementation 3. Minimization of det autom 4.
