One deterministic module has affine ranking function -1 * str + unknown-#length-unknown[str] + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[str] + -1 * start + i and consists of 8 locations. One deterministic module has affine ranking function -2 * start + 2 * i + 13 and consists of 9 locations. One deterministic module has affine ranking function unknown-#length-unknown[A] + -1 * start and consists of 5 locations. One deterministic module has affine ranking function j and consists of 6 locations. 7 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.4s and 13 iterations. TraceHistogramMax:4. Analysis of lassos took 10.6s. Construction of modules took 0.3s. Büchi inclusion checks took 1.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
