METHOD AND SYSTEM FOR ROBUST SOCIAL CHOICES AND VOTE ELICITATION

摘要

The present invention is a system, method and computer program for generating an optimal decision based on general, incomplete decision-making input, such as incomplete preferences. Input may be provided from a variety of entities (including human and computer entities). The present invention may be operable to utilize such input to make a set of decisions and an optimal decision may be efficiently generated, even if the input represents incomplete voter preferences. The present invention may also undertake a decision-making process that involves a facility to compute minimax regret and to elicit preferences from a voter. Preferences may be elicited by one or more queries posed to a voter about their pairwise preferences in such a way so as to maximally reduce minimax regret. The type of queries and order of queries posed may be determined in accordance with the most efficient decision-making process to arrive efficiently at the optimal decision. In this manner the present invention may guide the decision-making process to support and elicit efficient decision-making.
