Title:
GROUP DIVISION METHOD COMBINING SOCIAL RELATIONSHIP AND SELFISH PREFERENCE ORDER
Document Type and Number:
WIPO Patent Application WO/2021/197001
Kind Code:
A1
Abstract:
A group division method combining a social relationship and a selfish preference order, comprising the following steps: step 1, according to social values of users, simulating the selection of the user gathering into groups for sharing cost, to form a preliminary group; and step 2, formulating a combining and splitting rule according to a selfish preference order, and on the basis of the combining and splitting rule, combining or splitting the groups obtained in step 1, and upon reaching a Nash equilibrium point, ending the group combining or splitting, and obtaining a stable group. The method combines a social relationship and a selfish preference order in a scenario of static games of complete information, and accordingly finds a Nash equilibrium point, improving the stability of group division and eliminating extreme members, solving the problem regarding extreme users in a group, and improving the satisfaction of the group members for a recommendation result of the group.
