One deterministic module has affine ranking function unknown-#length-unknown[v] + -4 * j + -1 * v and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[v] + -2 * j and consists of 7 locations. One deterministic module has affine ranking function -4 * k + 2 * unknown-#length-unknown[v] + -1 * v and consists of 3 locations. One nondeterministic module has affine ranking function 2 * i + 1 and consists of 5 locations. 7 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.6s and 12 iterations.
