One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * s and consists of 6 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * s and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.2s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 5.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
