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 -1 * start + i + unknown-#length-unknown[str] and consists of 8 locations. One deterministic module has affine ranking function -1 * start + unknown-#length-unknown[str] + -1 * str and consists of 4 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 11.5s and 12 iterations. TraceHistogramMax:3. Analysis of lassos took 10.1s. Construction of modules took 0.3s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
