One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[x][x] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 6 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 unknown-#memory_int-unknown[y][y] and consists of 6 locations. One nondeterministic module has affine ranking function -1 * unknown-#memory_int-unknown[x][x] and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.4s and 10 iterations.
