One deterministic module has affine ranking function (((2 * x) + (-2 * z)) + 1) and consists of 4 locations. One deterministic module has affine ranking function (((2 * x) + (-2 * z)) + 1) and consists of 3 locations. One deterministic module has affine ranking function (z + (-1 * x)) and consists of 3 locations. One deterministic module has affine ranking function (y + (-1 * x)) and consists of 4 locations. One nondeterministic module has affine ranking function (((2 * x) + (-2 * z)) + 1) and consists of 3 locations. One nondeterministic module has affine ranking function (z + (-1 * x)) and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.6s and 7 iterations.
