One deterministic module has affine ranking function currentFloorID and consists of 45 locations. One deterministic module has affine ranking function doorState and consists of 3 locations. One deterministic module has 2-nested ranking function (if cleanupTimeShifts + -1 * i > 0 then 1 else 0), (if cleanupTimeShifts + -1 * i > 0 then cleanupTimeShifts + -1 * i else __cil_tmp4 + -1 * i) and consists of 4 locations. 9 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 75.7s and 10 iterations.
