One deterministic module has 3-nested ranking function (if 2 * z + 1 > 0 then 2 else (if 2 * y + 1 > 0 then 1 else 0)), (if 2 * z + 1 > 0 then 2 * z + 1 else (if 2 * y + 1 > 0 then 2 * y + 1 else 2 * x + 1)) and consists of 6 locations. One deterministic module has 3-nested ranking function (if 2 * z > 0 then 2 else (if 2 * y + 2 * z + 1 > 0 then 1 else 0)), (if 2 * z > 0 then 2 * z else (if 2 * y + 2 * z + 1 > 0 then 2 * y + 2 * z + 1 else 2 * x + 1)) and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 3 iterations.
