Multi-objective rapid genetic method for community network detection

The invention discloses a multi-objective rapid genetic method for community network detection. The method is used to search for community structures in complex community networks, and solves the problems of "premature" and low efficiency in the optimization process of traditional algorithms. The present invention transforms the problem of community division into a multi-objective optimization problem. Firstly, two objective functions of community score and community fitness are constructed, and an external elite gene bank is introduced to store non-inferior solutions with high fitness. For the external elite gene bank Existing duplicate individuals do not need to repeat decoding, calculate the fitness value of the individual and a series of processes, and then execute the genetic variation crossover operator to return a set of non-dominated solutions that are compromised between the two objective functions, and generate the adjacency of the graph after decoding Matrix, thus dividing a complex community network into multiple independent sub-networks. The simulation shows that the multi-objective fast genetic algorithm introduces the concept of external elite gene pool to greatly reduce the time complexity and improve the efficiency and speed of complex network detection.
