One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 6 locations. 4 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.2s and 7 iterations.
