In this paper we present and evaluate a general framework for the design of truthful auctions for matching agents in a dynamic, two-sided market. A single commodity, such as a resource or a task, is bought and sold by multiple buyers and sellers that arrive and depart over time. Our algorithm, Chain, provides the first framework that allows a truthful dynamic double auction (DA) to be construct...

This paper studies the impact of second-order uncertainty on the (ex-post) efficiency of the 0.5-double auction. We consider a discrete double auction model in which the seller’s valuation is either vs or vs and the buyer’s valuation is either vb or vb with 0 = vs < vb < vs < vb = 1. The buyer’s valuation and the seller’s valuation are private information. We further assume that the buyer’s bel...

Spectrum auction is an effective way to improve spectrum efficiency in cognitive networks. All traditional auction framework such as VCG price auction framework and second price auction framework face security risks. Collusion is the most important risk in multi-user cognitive networks. In this paper, we propose a security mechanism for the multi-user cognitive spectrum auction networks. This s...

In this paper, 2D seismic data and petrophysical logs of the Pabdeh Formation from four wells of the Mansuri oil field are utilized. ΔLog R method was used to generate a continuous TOC log from petrophysical data. The calculated TOC values by ΔLog R method, used for a multi-attribute seismic analysis. In this study, seismic inversion was performed based on neural networks algorithm and the resu...

1.1 INTRODUCTION Empirical research of online auctions has been growing steadily in the last several years. Online auctions are different from offline auctions in several important ways: They are usually much longer, bidders and sellers are anonymous, and the barriers of entry are much lower for both bidders and sellers. These differences lead to auction dynamics that can be very different from...

Recently, auction methods have been investigated as effective, decentralized methods for multi-robot coordination. Experimental research has shown great potential, but has not been complemented yet by theoretical analysis. In this paper we contribute a theoretical analysis of the performance of auction methods for multi-robot routing. We suggest a generic framework for auction-based multi-robot...

Its protocol calls for Annex B counties to reduce their average greenhouse gas emissions over 2008-2012 to at least five percent below 1990 levels. It adopted a " Plan of Action. " Since no details were given at these COPs, we have to design the mechanisms. 3 3. Which Trading Rule? • Bilateral Trading Is it inefficient due to mismatching? Does the revelation of contracted prices improve its eff...

This paper describes the use of a genetic algorithm (GA) to find optimal parameter-values for trading agents that operate in virtual online auction ‘e-marketplaces’, where the rules of those marketplaces are also under simultaneous control of the GA. The aim is to use the GA to automatically design new mechanisms for agent-based e-marketplaces that are more efficient than online markets designe...
