GN算法java实现

代码说明：

这是一个经典的社团划分，采用GN算法思想， 基本上是从昨天开始吧，着手复杂网络的GN算法，整个过程包括从GML文件中提取邻接矩阵数据，GN算法的实现，模块度的计算。 （1）GML文件的读取。做GN的时候首次知道GML（Graph Model Language）,GML (Graph Modelling Language): There are many different programs that work with graphs but almost all of them use their own file format. As a consequence, exchanging graphs between different programs is almost impossible. Simple tasks like exchange of data, externally reproducible results or a common benchmark suite are much harder than neccessary. Therefore, we have developed a new file format for the Graphlet system: GML. GML supports attaching arbitrary information to graphs, nodes and edges, and is therefore able to emulate almost every other format. 从上面的英文中我们可以知道，GML是一种文件格式，试图统一大家对图结构的表达形式。这样，会很方便大家的交互，比如程序的利用。我们主要工作是从GM
