One deterministic module has affine ranking function 2 * i + 1 and consists of 3 locations. One deterministic module has affine ranking function 2 * i + -2 * j + 1 and consists of 4 locations. One nondeterministic module has affine ranking function \old(array_size) + -2 * j and consists of 13 locations. One nondeterministic module has affine ranking function -4 * j + -1 * numbers + unknown-#length-unknown[numbers] and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.1s and 9 iterations.
