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[x][x] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[d][d] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 7 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 5 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[d][d] and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.6s and 8 iterations.
