兩臺處理機A 和B處理n個作業。設第i個作業交給機器
A 處理時需要時間ai，若由機器B 來處理，則需要時間bi。由于各作
業的特點和機器的性能關系，很可能對于某些i，有ai >=bi，而對于
某些j，j!=i，有aj<bj。既不能將一個作業分開由兩臺機器處理，也沒
有一臺機器能同時處理2 個作業。設計一個動態規劃算法，使得這兩
臺機器處理完成這n 個作業的時間最短（從任何一臺機器開工到最后
一臺機器停工的總時間）。研究一個實例：（a1,a2,a3,a4,a5,a6）=
（2,5,7,10,5,2）；（b1,b2,b3,b4,b5,b6）=（3,8,4,11,3,4）

The double-density DWT is an improvement upon the critically sampled DWT with important additional properties: (1) It employs one scaling function and two distinct wavelets, which are designed to be offset from one another by one half, (2) The double-density DWT is overcomplete by a factor of two, and (3) It is nearly shift-invariant. In two dimensions, this transform outperforms the standard DWT in terms of denoising however, there is room for improvement because not all of the wavelets are directional. That is, although the double-density DWT utilizes more wavelets, some lack a dominant spatial orientation, which prevents them from being able to isolate those directions.
