One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 7 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 5 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[x][x] and consists of 5 locations. 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[x][x] and consists of 7 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 5 locations. One nondeterministic module has affine ranking function -1 * unknown-#memory_int-unknown[x][x] and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.7s and 12 iterations.
