One deterministic module has affine ranking function unknown-#length-unknown[p] + -1 * p and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.3s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
