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 + 4294967295 * length1 and consists of 6 locations. One deterministic module has affine ranking function -1 * to + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.0s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 8.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
