Conference Paper
In this paper, we present a genetic algorithmic approach to automated auction mechanism design in the context of cat games. This is a follow-up to one piece of our prior work in the domain, the reinforcement learning-based grey-box approach [14]. Our experiments show that given the same search space the grey-box approach is able to produce better a...

In this paper, we introduce a novel, non-recursive, maximal matching algorithm for double auctions, which aims to maximize the amount of commodities to be traded. It differs from the usual equilibrium matching, which clears a market at the equilibrium price. We compare the two algorithms through experimental analyses, showing that the maximal match...

With the coming shift to cloud computing, cloud database is emerging to provide database service over the Internet. In the cloud-based environment, data are distributed at Internet scale and the system needs to handle a huge number of user queries simultaneously without delay. How data are distributed among the servers has a crucial impact on the q...
Article
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...

This paper analyzes the entrants to the 2007 TAC Market Design Game. We present a classification of the entries to the competition, and use 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 experimen...

Real market institutions, stock and commodity exchanges for example, do not occur in isolation. The same stocks and commodities may be listed on multiple exchanges, and traders who want to deal in those goods have a choice of markets in which to trade. While there has been extensive research into agent-based trading in individual markets, there is...
Article
Auctions play an important role in electronic commerce, and have been used to solve problems in distributed computing. Automated approaches to designing effective auction mechanisms are helpful in reducing the burden of traditional game theoretic, analytic approaches and in searching through the large space of possible auction mechanisms. This pape...
Conference Paper
Full-text available
This paper provides an overview of the experiments we carried out at the TREC 2010 Session Track. We propose an approach for interpreting reformulated queries by using query expansions derived from anchor logs which we envisage to be a potential alternative to query logs. We show that expansion with terms or phrases extracted from anchor logs impro...
Article
Full-text available
Auctions are markets with strict regulations governing the information available to traders in the market and the possible actions they can take. Since well designed auctions achieve desirable economic outcomes, they have been widely used in solving real-world optimization problems, and in structuring stock or futures exchanges. Auctions also provi...
Article
Full-text available
Many electronic markets are linked together into larger "network markets" where the links reflect constraints on traders. These constraints mean that a choice to trade in one market limits the trader's choice of other markets to use. This kind of network market is important because so many basic products, including gas, water, and electricity, are...
Conference Paper
Full-text available
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 wou...

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 inf...
Conference Paper

Modern large distributed applications, such as telecommunication and banking services, need to respond instantly to a huge number of queries within a short period of time. The data-intensive, query-intensive nature makes it necessary to build these applications in a distributed data environment that involves a number of data servers sharing service...

Full-text available
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 over...

Auctions, when well designed, result in desirable economic out-comes and have been widely used in solving real-world resource allocation problems, and in structuring stock or futures exchanges. The field of auction mechanism design has drawn much attention in recent years from economists, mathematicians, and computer scientists. In traditional auct...

Conference Paper

Real market institutions, stock and commodity exchanges for exam- ple, do not occur in isolation. Company stock is frequently listed on severa l stock exchanges, allowing traders to potentially trade such stock in different ma rkets. While there has been extensive research into agent-based trading in individual markets, there is little work on agen...
Conference Paper
Full-text available
In agent-based computational economics, many different trading strate- gies have been proposed. Given the kinds of market that such trading strategies are employed in, it is clear that the performance of the strat egies depends heavily on the behavior of other traders. However, most trading strategies are studied in homogeneous populations, and tho...

Real market institutions, stock and commodity exchanges for example, do not occur in isolation. Company stock is fre-quently listed on several stock exchanges, and futures ex-changes make it possible for dealers in a particular commod-ity to offset their risks by trading options in that commod-ity. While there has been extensive research into agent...

Auction mechanism design is a subeld of game theory dedi- cated to manipulating the rules of an auction so as to achieve specic goals. The complexity of the dynamics of auctions, especially continuous double auctions, makes it dicult to apply the usual analytic game-theoretic methods to do this. This paper takes an experimental approach, searching...

With the rise of ecommerce and the increase in volume of business pro- curement carried out electronically, double auctions have received much attention. This attention has been largely in the area of economics, but, increasingly, is in the area of computer science. However, there is no such thing as \the double auction". Instead there is a profusi...

This article proposes a modeling language for developing concurrent software, Object-Oriented Petri Nets (OOPN), which combines the maintainability and reusability of Object Orientation (OO) and the advantages of Petri Nets-a graphical interface and a sound theoretical background. By doing so, each benefits from the other and their negative aspects...
Article
The approach for concurrent system modeling based on the object-oriented petri nets (OPN) was introduced, which is the formalized description with combination of mathematics and graphics, not only reduces the complexity of the model, but also makes the modeled system with reusability and easy maintainability. The description of the object, establis...
