One deterministic module has affine ranking function unknown-#length-unknown[x] + -2 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * i + N and consists of 4 locations. One deterministic module has affine ranking function -1 * i + 2 * i and consists of 13 locations. One deterministic module has affine ranking function unknown-#length-unknown[x] + -2 * i and consists of 10 locations. One deterministic module has affine ranking function -1 * i + N and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[x] + -4 * i and consists of 4 locations. 7 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 28.9s and 14 iterations.
