Description: 递归与分治算法的应用.零件切割问题
给定一块宽度为W的矩形板，矩形板的高度不受限制。现需要从板上分别切割出n个高度为hi，宽度为wi的矩形零件。切割的规则是零件的高度方向与矩形板的高度方向保持一致。问如何切割使得所使用的矩形板的高度h最小？
-recursive algorithm with the partition of the application. Parts mutilation given a width of the rectangular plate W, the height of rectangular plate unrestricted. Board is required from the respective cut out n height of the hi, wi width of the rectangular parts. Cutting parts to the rules of the height of the rectangular plate with a high degree of consistent direction. Asked how cutting makes use of the rectangular plate height h minimum?
