One deterministic module has affine ranking function ((-1 * i) + len) and consists of 3 locations. One deterministic module has affine ranking function ((2 * j) + 1) and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.6s and 6 iterations.
