In this paper, we propose a bid optimizer for sponsored keyword search auctions which leads to better retention of advertisers by yielding attractive utilities to the advertisers without decreasing the revenue to the search engine. The bid optimizer is positioned as a key value added tool the search engine provides to the advertisers. The proposed bid optimizer algorithm transforms the reported...

In this paper, we propose a game theoretical model for joint scheduling and radio resource allocation in the downlink of a Long Term Evolution system, where Orthogonal Frequency Division Multiple Access is used as the multiple access scheme. The context is that of spectrum sharing, with multiple users competing for the simultaneous access to the radio channel. We first give a layered system rep...

objective: to classify different types of acute leukemia based on cooperative game theory and shapley value. materials and methods: in this study, patients data were collected from flow cytometry tests of the iran blood transfusion organization (ibto) have been used. 304 different diagnosed samples in 8 classes of acute leukemia were investigated. samples were initially in numerical format. i...

Cooperation and fairness in encounters with strangers are puzzling behaviors, since they contradict the law of natural selection. Compelling evidence shows that direct and indirect reciprocity and altruistic punishment are important mechanisms for the evolution of cooperation in the long-term. For short-interaction, cooperation and fairness are explained by theories which assume that individual...

This thesis applies evolutionary algorithms to tackle bargaining games. Evolutionary algorithms can discover efficient and stationary strategies for various bargaining games. Game-theoretic method requires a substantial amount of mathematical reasoning. Thus this method restricts to simple problems. Moreover, game-theoretic solutions rest on the crucial assumption that every player is perfectly...

This note investigates the noncooperative foundations of von Neumann-Morgenstern (vN-M) stable sets in voting games. To do so, we study subgame perfect equilibria of a noncooperative legislative bargaining game, based on underlying simple games. The following results emerge from such an exercise: Every stable set of the underlying simple game is the limit set of undominated pure-strategy Markov...

most of the time, groups/communities are involved in negotiations and disputations due to their various interests. they are always trying to pursuit their aspiration to embrace changes and influence on events. although sometimes these groups are not completely opposed to each other and their intention is just to get the desired results, almost always their conditions are in contrast with each o...

The deterministic coalition game theory is based on the presumption that all expected incomes of coalitions and individual players are exactly known even befor the bargaining process If we leave this presumption then we extend the original gamemodel into the fuzzy coalition game with vague i e fuzzy pay o s The vagueness of the pay o s leads to vagueness of some other concepts and prop erties l...

abstract a quantitative framework of combination of liner programming and cooperative game theory was used in this study to analyze and model cooperative contracts in production based on rural households' resources cooperation in firoozabad plain. revenues and costs in cooperation game theory have important rule to get agreement. transaction cost function was used in cooperative costs accountin...
