Algorithm for optimal winner determination in combinatorial auctions ✩
Combinatorial auctions, that is, auctions where bidders can bid on combinations of items, tend to lead to more efficient allocations than traditional auction mechanisms 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, we analyze existing approaches for tackling this problem: exhau...

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.

متن کاملAn Efficient Approximate Algorithm for Winner Determination in Combinatorial Auctions
This paper presents an approximate algorithm for the winner determination problem in combinatorial auctions, which is based on limited discrepancy search (LDS). Internet auctions have become an integral part of Electronic Commerce and can incorporate largescale, complicated types of auctions including combinatorial auctions, where multiple items are sold simultaneously and bidders can express c...
متن کاملCABRO: Winner Determination Algorithm for Single-unit Combinatorial Auctions
In this paper we present CABRO, an algorithm for solving the winner determination problem related to single-unit combinatorial auctions. The algorithm is divided in three main phases. The first phase is a pre-processing step with some reduction techniques. The second phase calculates an upper and a lower bound based on a linear programming relaxation in order to delete more bids. Finally, the t...
