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 3 terminating modules (1 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + length and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[arr2] + -4 * j and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 5.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
