Traveling Salesman Problem (TSP) has been an interesting problem for a long time in classical optimization techniques which are based on linear and nonlinear programming. TSP can be described as follows: Given a number of cities to visit and their distances from all other cities know, an optimal travel route has to be found so that each city is visited one and only once with the least possible distance traveled. This is a simple problem with handful of cities but becomes complicated as the number increases.

How the K-mean Cluster work Step 1. Begin with a decision the value of k = number of clusters Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following: Take the first k training sample as single-element clusters Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster. Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample. Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments.

压缩解压算法LZ77算法有许多派生算法(这里面包括 LZSS算法)。它们的算法原理上基本都相同，无论是哪种派生算法，LZ77算法总会包含一个动态窗口（Sliding Window）和一个预读缓冲器（Read Ahead Buffer）。动态窗口是个历史缓冲器，它被用来存放输入流的前n个字节的有关信息。一个动态窗口的数据范围可以从 0K 到 64K，而LZSS算法使用了一个4K的动态窗口。预读缓冲器是与动态窗口相对应的，它被用来存放输入流的前n个字节，预读缓冲器的大小通常在0 – 258 之间。这个算法就是基于这些建立的。用下n个字节填充预读缓存器（这里的n是预读缓存器的大小）。在动态窗口中寻找与预读缓冲器中的最匹配的数据，如果匹配的数据长度大于最小匹配长度 （通常取决于编码器，以及动态窗口的大小，比如一个4K的动态窗口，它的最小匹配长度就是2），那么就输出一对〈长度（length），距离（distance）〉数组。长度(length)是匹配的数据长度，而距离(distance)说明了在输入流中向后多少字节这个匹配数据可以被找到。

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
