This paper analyzes the entrants to the 2007 TAC Market Design competition. It presents a classification of the entries to the competition , and uses this classification to compare these entries. The paper also attempts to relate market dynamics to the auction rules adopted by these entries and their adaptive strategies via a set of post-tournament(More)
Auction mechanism design is a subfield of game theory dedicated to manipulating the rules of an auction so as to achieve specific goals. The complexity of the dynamics of auctions, especially continuous double auctions, makes it difficult to apply the usual analytic game-theoretic methods to do this. This paper takes an experimental approach, searching a(More)
This paper presents an analysis of entries in the first TAC Market Design Competition final that compares the entries across several scenarios. The analysis complements previous work analyzing the 2007 competition, demonstrating some vulnerabilities of entries that placed highly in the competition. The paper also suggests a simple strategy that would have(More)
Real market institutions, stock and commodity exchanges for example , do not occur in isolation. Company stock is frequently listed on several stock exchanges, allowing traders to potentially trade such stock in different markets. While there has been extensive research into agent-based trading in individual markets, there is little work on agents that(More)

Search applications have become very popular over the last two decades, one of the main drivers being the advent of the Web. Nevertheless, searching on the Web is very different to searching on smaller, often more structured collections such as digital libraries, local Web sites, and intranets. One way of helping the searcher locating the right information(More)
For a number of years we have been working towards the goal of automatically creating auction mechanisms, using a range of techniques from evolutionary and multi-agent learning. This paper gives an overview of this work. The paper presents results from several experiments that we have carried out, and tries to place these in the context of the overall task(More)
Traders that operate in markets with multiple competing marketplaces must often choose with which marketplace they will trade. These choices encourage marketplaces to seek competitive advantages against each other by adjusting various parameters, such as the price they charge, or how they match buyers and sellers. Traders can take advantage of this(More)
