提供一种求解最优哈密尔顿的算法---三边交换调整法，要求在运行jiaohuan3（三交换法）之前，给定邻接矩阵C和节点个数N，结果路径存放于R中。 bianquan.m文件给出了一个参数实例，可在命令窗口中输入bianquan,得到邻接矩阵C和节点个数N以及一个任意给出的路径R,，回车后再输入jiaohuan3,得到了最优解。 由于没有经过大量的实验，又是近似算法，对于网络比较复杂的情况，可以尝试多运行几次jiaohuan3,看是否能到进一步的优化结果。 (Provide an optimal algorithm Hamilton- trilateral exchange Adjustment Act, requiring running jiaohuan3 (c exchange) before a given adjacency matrix C and the node number N, the results of the path stored in the R in. bianquan.m document gives examples of a parameter can be in the command window, type bianquan, be the adjacency matrix C and the node number N and an arbitrary given path R,, carriage return after the input jiaohuan3, have been the optimal solution . After the absence of a large number of experiments, it is approximate algorithm, for more complex network situations, you can try to run several jiaohuan3, can look to further optimize the results.)

Matlab版俄罗斯方块，个人一直认为，这个游戏或者说这个程序很经典！ 如果你能掌握这个程序，你对Matlab的外功已经不成问题，回家修炼一下内功，就能毕业了！！ 不说别的，先来玩玩，别忘了把音箱打开！感受儿时的乐趣 程序作者：Pascal Getreuer (Matlab version of Tetris, individuals have always thought that this game or that the program was classic! If you can master this program, you have no problem Matlab' s external work, home practice about internal strength, we can graduate! ! If nothing else, the first to play, do not forget to turn on speakers! Experience the fun process of childhood: Pascal Getreuer)

三步法哪l是一种较好的搜索算法，快速而且高效，它是在对数法的基础上对 其进行了改进，提出在每一步搜索后搜索步长均减半的算法。它基本保持了FS的 性能，但其计算量只有FS的10％左右。TSS在会议电视和可视电话中应用较多， 它通过三步搜索，逐步较小搜索步长。若最大搜索范围为士7，搜索精度取一个像 素，则步长为4、2、1，共需三步即可满足要求，从而得名。 (L three-step method which is a better search algorithm, fast and efficient, it is on the basis of the number of law be improved, made in every step of the search after the search step of the algorithm are reduced by half. It basically maintained the performance of FS, but the calculation is only about 10 of FS. TSS at the meeting on television and video telephony in the application of more three-step search through progressively smaller search step. If the maximum search range of disabilities 7, search for a pixel accuracy, the step size for the 4,2,1, a total of three steps to meet the requirements, thus its name.)
