英文摘要：

The dynamic community detection has been an important research direction of complex network and the detection algorithm is a crucial core issue. To improve the accuracy of the community detection result, a self-adapted differential evolution algorithm for dynamic community detection based on the theory of differential evolution is presented. The difference between the networks from one timeslot to successive one is the optimal objective of the algorithm, which has been realized by both maximizing the snapshot cost of the current timeslot and minimizing the temporal cost between neighboring timeslot. synthetic data set and real-life data set demonstrate that the efficiency and accuracy complex networks by using SDEDCD algorithm are higher than those obtained by the Experimental results on of community detection in other two algorithms.
