One deterministic module has affine ranking function -8 * i + 9 * unknown-#length-unknown[x] and consists of 5 locations. One deterministic module has affine ranking function 9 + -2 * i and consists of 4 locations. One deterministic module has affine ranking function -2 * i + 7 and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 23.7s and 11 iterations.
