One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[z_ref][z_ref] + unknown-#memory_int-unknown[x_ref][x_ref] 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. 4 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.9s and 7 iterations.
