Algorithms for Distributed Winner Determination in Combinatorial Auctions
نویسندگان
چکیده
The problem of optimal winner determination in combinatorial auctions consists of finding the set of bids that maximize the revenue for the sellers. Various solutions exist for solving this problem but they are all centralized. That is, they assume that all bids are sent to a centralized auctioneer who then determines the winning set of bids. In this paper we introduce the problem of distributed winner determination in combinatorial auctions which eliminates the centralized auctioneer. We present a set of distributed search-based algorithms for solving this problem and study their relative tradeoffs.

Winner Determination in Combinatorial Auctions using Hybrid Ant Colony Optimization and Multi-Neighborhood Local Search
A combinatorial auction is an auction where the bidders have the choice to bid on bundles of items. The WDP in combinatorial auctions is the problem of finding winning bids that maximize the auctioneer’s revenue under the constraint that each item can be allocated to at most one bidder. The WDP is known as an NP-hard problem with practical applications like electronic commerce, production manag...
متن کاملOn the Sensitivity of Incremental Algorithms for Combinatorial Auctions
Despite the large amounts of runtime needed to adequately solve a combinatorial auction (CA), existing iterative CA auction protocols require winner determination during every round of bid submissions. Using existing algorithms for winner determination will cause a timing bottleneck during the winner determination phase. Furthermore, there has recently been work which models the formation of su...
متن کاملInteger Programming for Combinatorial Auction Winner Determination
Combinatorial auctions are important as they enable bidders to place bids on combinations of items; compared to other auction mechanisms, they often increase the efficiency of the auction, while keeping risks for bidders low. However, the determination of an optimal winner combination in combinatorial auctions is a complex computational problem. In this paper we (i) compare recent algorithms fo...

متن کاملAn Algorithm for Optimal Winner Determination in Combinatorial Auctions
Combinatorial auctions, i.e. auctions where bidders can bid on combinations of items, tend to lead to more efficient allocations than traditional auctions in multi-item auctions where the agents' valuations of the items are not additive. However, determining the winners so as to maximize revenue is NP-complete. First, existing approaches for tackling this problem are reviewed: exhaustive enumer...
