One deterministic module has affine ranking function x and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.0s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 2.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
