One deterministic module has affine ranking function -2 * op1 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op2 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 5 and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.0s and 4 iterations.
