Information processing device

Abstract

Provided is an information processing device that, by means of a novel technique, is capable of evaluating a user on the basis of the results of actions performed between users or user groups. The information processing device does the following: obtains action results data that indicates the results of actions performed between a plurality of users or user groups; performs multiple executions of trace processing, which consists of start-point selection processing that randomly selects a target from among the plurality of users or user groups and target selection processing that repeats, until a prescribed condition is met, processing that newly selects as the next target another party to the action that the current target is performing, on the basis of the action results data; and, for each of the plurality of users or user groups, calculates an evaluation value for the user or user group in accordance with the number of times users or user groups were selected as a target in the multiple iterations of trace processing.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, a program, and an information storage medium in which evaluation of actions performed among a plurality of users or groups of users is performed. Background technique [0002] For example, in a game competition, when some actions are performed among multiple users (or groups of users), it is sometimes desirable to evaluate the results of the actions and perform rankings. For example, in a game competition, it is desirable to implement processing for calculating rankings of all users and finding a user having power substantially equal to that of a specific user based on victory and defeat in the results of a competition between various users. Specifically, when a large number of users participate in a game, each user cannot directly care about all remaining users, but only cares about some of all users. In the case described thus, it is difficult to sim...

However, if some player wins over a different player who has a higher rank than his own rank (i.e., a different player has a higher rank than the player's own rank), then a large number of points are awarded
