One deterministic module has affine ranking function unknown-#length-unknown[a] + -4 * i and consists of 5 locations. One deterministic module has affine ranking function -16 * j + unknown-#length-unknown[array] and consists of 14 locations. One deterministic module has affine ranking function size + -1 * i and consists of 6 locations. One nondeterministic module has affine ranking function array + 4 * j and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 18 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.6s and 9 iterations.
