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 -2 * j + unknown-#length-unknown[v] and consists of 7 locations. One deterministic module has affine ranking function -4 * k + unknown-#length-unknown[v] and consists of 4 locations. One deterministic module has affine ranking function i and consists of 5 locations. One nondeterministic module has affine ranking function 4 * i + j and consists of 8 locations. One nondeterministic module has affine ranking function i and consists of 3 locations. One nondeterministic module has affine ranking function 2 * i + 1 and consists of 5 locations. 13 modules have a trivial ranking function, the largest among these consists of 31 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 74.1s and 21 iterations.
