Description: 98年全国大学生数学建模竞赛B题“水灾巡视问题”，是一个推销员问题，本题有53个点，所有可能性大约为exp(53),目前没有好方法求出精确解，既然求不出精确解，我们使用模拟退火法求出一个较优解,将所有结点编号为1到53,1到53的排列就是系统的结构,结构的变化规则是:从1到53的排列中随机选取一个子排列,将其反转或将其移至另一处,能量E自然是路径总长度。具体算法描述如下：步1： 设定初始温度T，给定一个初始的巡视路线。步2 ：步3 --8循环K次步3：步 4--7循环M次步4：随机选择路线的一段步5：随机确定将选定的路线反转或移动，即两种调整方式：反转、移动。步6：计算代价D，即调整前后的总路程的长度之差步7：按照如下规则确定是否做调整：如果D<0,则调整如果D>0,则按照EXP(-D/T)的概率进行调整步8:T*0.9-->T,降温-98 National Mathematical Contest in Modeling B and that the "flood inspections", is a salesman problem, and that is 53 points, all possibilities about exp (53), there is no good way to get accurate solutions, since no exact solution for, we used simulated annealing France obtained an optimum solution to all nodes to a number of 53 to 53.1 is with the system structure, changes in the structure of the rules is : from 1-53 with a randomly selected with a son, to reverse or to move it to another, the energy E is the natural path length. The specific algorithm is described as follows : Step 1 : The initial set temperature T, given an initial inspection line.

Description: README for mrouted, the DVMRP Multicast Routing Daemon ====================================================== mrouted is an implementation of the DVMRP multicast routing protocol. It turns a UNIX workstation into a DVMRP multicast router with tunnel support, in order to cross non-multicast-aware routers. DVMRP is a distance vector based protocol, derived from RIP, suitable for closely located multicast users in smaller networks. It simply floods all multicast streams to all routers, i.e. implicit join. This is also known as "flood and prune" since you can opt out from groups you do not want. For a detailed explanation of the protocol, consult RFC 1075. Platform: |

Description: 等值线
在科学计算和现实生活中，常常会遇到y=f(t)这类函数关系，例如，正弦、余弦等等。函数y=f(t)往往是以离散的观测值形式f(ti)(i=1,....N)表现出来的。例如，令股民朋友如醉如痴的K线图，与千家万户性命攸关的河流水位曲线图等等。离散函数关系有不少数据处理课题，例如，数据拟合、插值和平滑等等。最令人兴奋的还是预测，如果股民朋友能够准确把握y=f(t)的走向，钞票就会源源不断涌入口袋。如果水文学家能够准确预测河流水位暴涨的过程，可以大量减少生命和财产损失。
所谓画曲线就是描绘y=f(t)的图象，在本书我们将通过图象绘制直观地了解观测值的变化和数据处理方法的效果-contours in scientific computing and real-life, we will often encounter y = f (t) such a function, such as sine, cosine and so on. Function y = f (t) tend to be discrete observation form f (t) (i = 1 ...... N) the performance. For example, investors simply friends of K map, and the millions of lives at stake curve of water levels in rivers and so on. Discrete function of a number of data-processing tasks, such as data fitting, interpolation and smoothing and so on. Most exciting is predicted that if shareholders friends to accurately grasp y = f (t) trend, money will continue to flood into pockets. If hydrologists can accurately predict river levels rose process, a significant reduction in loss of life and property. The so-called curve is painting depicting y = f (t) of the image, in this Platform: |
