中文说明：代码里有很完整的注释和解释，采用加权网络中节点强度和权重都是幂率分布的模型，添加噪声处理，DC-DC部分采用定功率单环控制，快速扩展随机生成树算法，通过matlab代码。
English Description：
Code is a complete annotated and explained, the weighted network node strength and weight are power-law distribution model and add noise to deal with, DC-DC part of the constant power single loop control, the rapid expansion of the random spanning tree algorithm, through MATLAB code.
