One nondeterministic module has affine ranking function \old(y1) and consists of 10 locations. One nondeterministic module has affine ranking function y2 and consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.7s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 6.7s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
