One deterministic module has affine ranking function 2 * s + length2 and consists of 4 locations. One nondeterministic module has affine ranking function 2 * s + 1 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.5s and 6 iterations.
