Abstract
Community detection is a basic tool to analyze complex networks. However, there are many community detection methods for unipartite networks while just a few methods for bipartite networks (BNs). In this paper, we propose a memetic algorithm (MACD-BNs) to identify communities in BNs. We use MACD-BNs to optimize two extended measures, namely Baber modularity (Q B ) and modularity density (Q D ), on real-life and synthetic networks respectively so as to compare their performance. We conclude that Q D are more effective than Q B when the size of communities is heterogeneous while Q B is more suitable to detect communities with similar size. Besides, we also make a comparison between MACD-BNs and other community detection method and the results show the effectiveness of MACD-BNs.
