One deterministic module has affine ranking function -1 * i + len and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + 2 * j and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.2s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 7.5s. Construction of modules took 0.0s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
