One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function 7 + -2 * splverifierCounter and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.9s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 2.0s. Construction of modules took 0.0s. Büchi inclusion checks took 1.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
