One deterministic module has affine ranking function -1 * i + length and consists of 5 locations. One deterministic module has 2-nested ranking function (if -2 * unknown-#memory_int-unknown[arr][arr] + 1 > 0 then 1 else 0), (if -2 * unknown-#memory_int-unknown[arr][arr] + 1 > 0 then -2 * unknown-#memory_int-unknown[arr][arr] + 1 else -2 * j + 2 * length) and consists of 2 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.0s and 4 iterations.
