One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] + -1 * z and consists of 6 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[z_ref][z_ref] + unknown-#memory_int-unknown[y_ref][y_ref] and consists of 4 locations. 5 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.0s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 14.6s. Construction of modules took 0.2s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 1.
