One deterministic module has affine ranking function ((((long) 2 * x) + ((long) -2 * z)) + 1) and consists of 4 locations. One deterministic module has affine ranking function ((((long) 2 * x) + ((long) -2 * z)) + 1) and consists of 3 locations. One deterministic module has affine ranking function (y + ((long) -1 * x)) and consists of 3 locations. One nondeterministic module has affine ranking function ((((long) 2 * x) + ((long) -2 * z)) + 1) and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.2s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 2.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
