de Weerdt, M.M. (author), Gerding, Enrico (author), Stein, Sebastian (author)Rank aggregation is the problem of generating an overall ranking from a set of individual votes which is as close as possible to the (unknown) correct ranking. The challenge is that votes are often both noisy and incomplete. Existing work focuses on the most likely ranking for a particular noise model. Instead, we focus on minimising the error,...abstract 2016

Hindriks, K.V. (author), Tykhonov, D. (author), De Weerdt, M.M. (author)A result of Bulow and Klemperer has suggested that auctions may be a better tool to obtain an efficient outcome than negotiation. For example, some auction mechanisms can be shown to be efficient and strategy-proof. However, they generally also require that additional constraints are met which are not always easy to guarantee in practice. It...book chapter 2010

Wu, M. (author), De Weerdt, M.M. (author), La Poutré, H. (author)In this paper, we present an automated multi-agent multi-issue negotiation solution to solve a resource allocation problem. We use a multilateral negotiation model, by which three agents bid sequentially in consecutive rounds till some deadline. Two issues are bundled and negotiated concurrently, so win-win opportunities can be generated as...book chapter 2009

Jalilzadeh, B. (author), Planken, L. (author), De Weerdt, M.M. (author)We consider online mechanism design without money, where agents are allowed to trade items with other agents, in an attempt to improve their own allocation. In an off-line context, this problem is known as the House Allocation Problem (HAP). We extend HAP to an online problem and call it the Online House Allocation Problem (OHAP). In OHAP,...book chapter 2010

Stranders, R. (author), De Weerdt, M.M. (author), Witteveen, C. (author)In an open Multi-Agent System, the goals of agents acting on behalf of their owners often conflict with each other. Therefore, a personal agent protecting the interest of a single user cannot always rely on them. Consequently, such a personal agent needs to be able to reason about trusting (information or services provided by) other agents....book chapter 2008

Grootenboers, F. (author), De Weerdt, M.M. (author), Zargayouna, M. (author)Demand responsive transportation has the potential to provide efficient public door-to-door transport with a high quality. In currently implemented systems in the Netherlands, however, we observe a decrease in the quality of service (QoS), expressed in longer travel times for the customers. Currently, generally one transport company is...book chapter 2010

Máhr, T. (author), De Weerdt, M.M. (author)To come to a deal, a bargaining process can sometimes take a long time. An auction may be a faster, but existing auction models cannot cope with situations where money is not an issue, or where it is difficult to express the utility of all participants in a monetary domain. We propose a modified Vickrey auction based only on preferences over the...book chapter 2007

De Weerdt, M.M. (author), Zhang, Y. (author)In games where agents are asked to declare their available resources, they can also strategize over this declaration. Surprisingly, not in all such games a VCG payment can be applied to construct a truthful mechanism using an optimal algorithm, though such payments can prevent under-reporting of resources. We show this for the problem of...book chapter 2010

Zutt, J. (author), Van Gemund, A.J.C. (author), De Weerdt, M.M. (author), Witteveen, C. (author)An important problem in transportation is how to ensure efficient operational route planning when several vehicles share a common road infrastructure with limited capacity. Examples of such a problem are route planning for automated guided vehicles in a terminal and route planning for aircraft taxiing at airports. Maintaining efficiency in such...book chapter 2010

de Nijs, F. (author), de Weerdt, M.M. (author), Spaan, M.T.J. (author)Demand response refers to the concept that power consumption should aim to match supply, instead of supply following demand. It is a key technology to enable the successful transition to an electricity system that incorporates more and more intermittent and uncontrollable renewable energy sources. For instance, loads such as heat pumps or...book chapter 2019

Máhr, T. (author), De Weerdt, M.M. (author)Multi-attribute auctions allow negotiations over multiple attributes besides price. For example in task allocation, service providers can define their service by means of multiple attributes, such as quality of service, deadlines, or delay penalties. Auction mechanisms assume that the players have evaluation functions over the space of...conference paper 2006

De Weerdt, M.M. (author), Bos, A. (author), Tonino, J.F.M. (author), Witteveen, C. (author)The promise of multi-agent systems is that multiple agents can solve problems more efficiently than single agents can. In this paper we propose a method to implement cooperation between agents in the planning phase, in order to achieve more cost-effective solutions than without cooperation. Two results are presented: First of all, we introduce a...conference paper 2000

De Weerdt, M.M. (author), Tonino, J.F.M. (author), Witteveen, C. (author)In this paper we will use the framework to study cooperative heuristic multi-agent planning. During the construction of their plans, the agents use a heuristic function inspired by the FF planner (l3l). At any time in the process of planning the agents may exchange available resources, or they may request an agent to produce a missing resource....conference paper 2001

Traditional efforts hereto are mainly of a regulatory nature, whereas we propose charging the service-providers (agents)...conference paper 2012

Zhang, Y. (author), De Weerdt, M.M. (author)When information or control in a multiagent system is private to the agents, they may misreport this information or refuse to execute an agreed outcome, in order to change the resulting end state of such a system to their benefit. This may result in execution failures. When only information is private, mechanisms such as VCG use payments to...conference paper 2009

De Weerdt, M.M. (author), Gerding, E.H. (author), Stein, S. (author), Robu, V. (author), Jennings, N.R. (author)En-route charging stations allow electric vehicles to greatly extend their range. However, as a full charge takes a considerable amount of time, there may be significant waiting times at peak hours. To address this problem, we propose a novel navigation system, which communicates its intentions (i.e., routing policies) to other drivers. Using...conference paper 2013
