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 5 terminating modules (2 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[nondetString2] + -1 * nondetString2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s1 + unknown-#length-unknown[nondetString1] and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.4s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 6.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
