One deterministic module has affine ranking function unknown-#length-unknown[x] + -4 * i + -1 * x and consists of 5 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] + -1 * x and consists of 4 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] and consists of 5 locations. One deterministic module has affine ranking function 3 * i + -2 * i and consists of 13 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] and consists of 4 locations. 9 modules have a trivial ranking function, the largest among these consists of 24 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 27.4s and 15 iterations. TraceHistogramMax:3. Analysis of lassos took 25.1s. Construction of modules took 0.8s. Büchi inclusion checks took 1.3s. Highest rank in rank-based complementation 3. Minimization of det autom 14.
