One deterministic module has affine ranking function N + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * l + N and consists of 5 locations. One deterministic module has affine ranking function N + -1 * j and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 56.3s and 4 iterations.
