A method determines a sequence for drilling holes in a workpiece according to a pattern by first partitioning the holes in the pattern into packets. A global sequence of the packets is determined by solving a global traveling salesman problem (TSP), and a local sequence of the holes in each packet is determined by solving a local TSP for each packet. Then, the local sequences of the holes are joined according to the global sequence of the packets to determine a complete sequence for drilling the holes.
