One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[y_ref][y_ref] + unknown-#memory_int-unknown[x_ref][x_ref] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 8 locations. 2 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.3s and 6 iterations.
