One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op6 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.0s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 3.9s. Construction of modules took 0.0s. Büchi inclusion checks took 1.5s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
