One deterministic module has affine ranking function -2 * op1 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op2 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 5 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.8s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 3.0s. Construction of modules took 0.4s. Büchi inclusion checks took 7.9s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
