One deterministic module has affine ranking function -2 * unknown-#memory_int-unknown[y_ref][y_ref] + 2147483647 and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.4s and 3 iterations.
