Problems solved by technology

[0003] However, the current techniques for analyzing the evolution of network cooperation through evolutionary game theory mainly improve the cooperation level of the network by optimizing the network structure and changing the strategy update formula, without considering the interaction between different individuals and neighbors in the network. difference
This method leads to the problem of low efficiency of network information sharing and waste of resources.

Abstract

The invention relates to a method for improving the network information sharing level based on an evolutionary game theory, and the method comprises the steps: initializing a network structure, and determining the network structure, the number of nodes in a network, and the average degree dmean of the network; defining an income matrix and a game strategy of the nodes; initializing system parameters, and determining the number e of evolutionary gaming; each node games with a neighbor node to obtain accumulated income; the node degree is introduced into strategy updating of the node, and node revenue used for strategy updating is adjusted; each node randomly selects neighbor nodes for strategy learning; updating the strategy of each node in the network; and judging whether the node reaches the maximum evolution frequency, and finally calculating the final cooperation rate of the network. By adopting the method, the node degree of the individual in the network is added into the strategy updating process, the cooperative behavior in the network is effectively promoted, and the network information sharing level is improved.

Description

technical field [0001] The present application relates to the technical field of network cooperation evolution analysis, and in particular to a method, device, computer equipment and storage medium for improving network information sharing level based on evolutionary game theory. Background technique [0002] With the continuous development of network technology, information sharing between individuals can break the information islands of distributed systems and improve the operating efficiency of the system. However, individuals need to pay for sharing their own information, and they can get other individuals without sharing their own information. Therefore, due to the selfishness of individuals, there will be a cooperation dilemma in the process of information sharing among individuals, and it becomes a rational choice not to share their own information with other individuals. On this basis, the evolution analysis technology of network cooperation emerged. Evolutionary gam...
