One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[x][x] + 1 + -2 * unknown-#memory_int-unknown[y][y] and consists of 6 locations. One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[x][x] + 1 + -2 * unknown-#memory_int-unknown[y][y] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[z][z] and consists of 4 locations. One nondeterministic module has affine ranking function 2 * unknown-#memory_int-unknown[x][x] + 1 + -2 * unknown-#memory_int-unknown[y][y] and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 52.3s and 6 iterations.
