One deterministic module has affine ranking function array_size + -1 * i and consists of 3 locations. One deterministic module has affine ranking function array_size + -1 * j and consists of 4 locations. One nondeterministic module has affine ranking function -1 * a + -4 * j + unknown-#length-unknown[__builtin_alloca (array_size * sizeof(int))] and consists of 6 locations. 5 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.2s and 10 iterations.
