One deterministic module has affine ranking function length + -1 * i and consists of 5 locations. One deterministic module has 2-nested ranking function (if -2 * unknown-#memory_int-unknown[arr][arr] + length > 0 then 1 else 0), (if -2 * unknown-#memory_int-unknown[arr][arr] + length > 0 then -2 * unknown-#memory_int-unknown[arr][arr] + length else 2 * length + -2 * j) 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 4.8s and 4 iterations.
