Community is a network's subgraph where vertices share similar properties and reflect interesting characteristics for understanding complex networks more closely. Therefore, community structure analysis is important in understanding and exploring complex networks and helps in describing relationship among nodes in a network. However, efficiently finding communities in a complex network still remains an open problem. Since there exists numerous ways of defining a community, existing strategies have adopted different parameters to reflect varied behavior of a community structure and trying to give a coarser or finer community distribution.
