人工蜂群算法

有关复杂网络研究的ppt,是从事复杂网络研究人员难得的资料。(Complex network-related research ppt, is engaged in a rare complex network of information researchers.)

此源码是文档simulation.rar__关于光孤子在光纤耦合器中传输的仿真研究的matlab程序(This source is a document about simulation.rar__ optical soliton in optical fiber coupler in the transmission process simulation matlab)

首先从n个数据对象任意选择 k 个对象作为初始聚类中心；而对于所剩下其它对象，则根据它们与这些聚类中心的相似度（距离），分别将它们分配给与其最相似的（聚类中心所代表的）聚类；然后再计算每个所获新聚类的聚类中心（该聚类中所有对象的均值）；不断重复这一过程直到标准测度函数开始收敛为止。一般都采用均方差作为标准测度函数. k个聚类具有以下特点：各聚类本身尽可能的紧凑，而各聚类之间尽可能的分开。(First, a data object from the n choose k objects as initial cluster centers and for the rest of the other objects, according to their similarity with the cluster center (distance), respectively, assign them to their most similar (represented by cluster center) clustering then calculated for each cluster center received a new clustering (all objects in the cluster mean) repeats this process until the convergence criteria begin until the measure function. Standard deviation is generally used as a standard measure function. K a cluster has the following characteristics: the cluster itself as a compact, but separated as much as possible between each cluster.)

说明：  离散系统的差分方程，该程序可以得出差分方程！结果挺好的！(equation)

Kmeans聚类算法以及改进的Kmeans聚类算法，包含收集的很多论文(Kmeans clustering algorithm and Kmeans clustering algorithm and improved, including a lot of paper collection)

In this file, the case of polymer casting is considered as an unsteady state heat transfer problem. The explicit scheme of finite difference approach is considered to solve the governing partial differential equation in one dimensional (radial) cylindrical coordinates.
