One deterministic module has affine ranking function -2 * i + 19 and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + 2 * j and consists of 3 locations. 5 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.9s and 8 iterations.
