Public opinion information and viewpoint co-evolution model construction method based on evolutionary game

Abstract

The invention provides a public opinion information and viewpoint co-evolution model construction method based on an evolutionary game. The method belongs to the field of evolutionary games, and comprises the following steps: step 1, selecting a 100 * 100 regular mesh network as a social network model, enabling each individual on the social network to occupy one mesh in the regular network, and endowing each individual with an attribute value; step 2, taking each individual as a central individual, and carrying out cyclic collaborative evolution on the central individual; 3, a timer is used for timing operation, in each round of evolution process, when the specified time is up, the collaborative evolution process is stopped, information is infiltrated into the individual with the highest reputation value, and meanwhile the reputation value of the individual is increased; then, the collaborative calculation operation is continued; and step 4, circularly carrying out the step 2 and the step 3 until the collaborative evolution of all central individuals is completed. The method promotes emergence of positive cooperation behaviors among individuals in the social network, and has practicability.

Description

Technical field [0001] The invention belongs to the technical field of evolutionary games, and specifically relates to a method for constructing a co-evolution model based on evolutionary game-based public opinion information and opinions. Background technique [0002] The research on the dissemination of public opinion information on social networks and the evolution of individual opinions mainly describes and analyzes the process of constructing mutual relationships between the different game behaviors of individuals in social groups, the mutual influence of different opinions between individuals and the process of reaching consensus, and individual behaviors And the influence process of attitude on the spread of public opinion information, etc. From an economic perspective, information diffusion is greatly affected by the decision-making and behavior of network users and their socio-economic connections. Game theory, as one of the important theories, mainly describes the pote...

Problems solved by technology

[0005] From the existing related work, it can be concluded that the problems existing in the existing technology are: the research on the evolutionary game to promote the emergence of cooperative behavior on complex networks does not have sufficient practical significance; only the impact of the game on individual behavior is studied, and the default The behavior and attitude of individuals in the social network are consistent, which does not reflect the characteristics of people's "inconsistency in knowledge and action" in reality; in the game process, the system's incentive mechanism for individual cooperation behavior and punishment mechanism for betrayal behavior are not perfect
