One deterministic module has affine ranking function -1 * v + -4 * j + unknown-#length-unknown[v] and consists of 5 locations. One deterministic module has affine ranking function -4 * j + unknown-#length-unknown[v] and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[v] + 16 * i and consists of 6 locations. One deterministic module has affine ranking function -1 * v + -4 * k + unknown-#length-unknown[v] and consists of 3 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[v] + 2 * i and consists of 6 locations. One nondeterministic module has affine ranking function i and consists of 4 locations. 11 modules have a trivial ranking function, the largest among these consists of 25 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 31.8s and 18 iterations.
