One deterministic module has affine ranking function 15 * unknown-#length-unknown[A] + -2 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[str] + -1 * str and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[A] + -1 * start and consists of 6 locations. One deterministic module has affine ranking function j and consists of 6 locations. 10 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 30.4s and 15 iterations. TraceHistogramMax:8. Analysis of lassos took 28.7s. Construction of modules took 0.4s. Büchi inclusion checks took 1.1s. Highest rank in rank-based complementation 3. Minimization of det autom 5.
