Synthetic data 1: A network contains nine communities. The nodes insides the community are closely connected, and the nodes between communities are sparsely connected.Synthetic data 2: A network contains nine communities. There are some nodes that connect the nodes in different communities at the same time.

合成数据1：网络包含九个社区。社区内部的节点紧密相连，而社区之间的节点稀疏连接。合成数据2：网络包含九个社区。存在一些节点同时连接不同社区中的节点。
