One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[y_ref][y_ref] and consists of 5 locations. One deterministic module has affine ranking function -2 * unknown-#memory_int-unknown[y_ref][y_ref] + 4294967293 and consists of 6 locations. 6 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 23.3s and 10 iterations.
