Jansen, B. (author)Spreadsheets are widely used within companies and often form the basis for business decisions. Numerous cases are known where incorrect information in spreadsheets lead to incorrect decisions. Such cases underline the relevance of research on the professional use of spreadsheets. Recently a new dataset became available for research, containing...conference paper 2015

Roy, S. (author)Business rules represent the knowledge that guides the operations of a business organization. They are implemented in software applications used by organizations, and the activity of extracting them from software is known as business rule mining. It has various purposes amongst which migration and generating documentation are the most common....conference paper 2015

Yang, J. (author), Hauff, C. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)Collaborative Question Answering (cQA) platforms are a very popular repository of crowd-generated knowledge. By formulating questions, users express needs that other members of the cQA community try to collaboratively satisfy. Poorly formulated questions are less likely to receive useful responses, thus hindering the overall knowledge generation...conference paper 2014

Ströhle, P. (author), Gerding, E.H. (author), De Weerdt, M.M. (author), Stein, S. (author), Robu, V. (author)We design new algorithms for the problem of allocating uncertain, flexible, and multi-unit demand online given uncertain supply, in order to maximise social welfare. The algorithms can be seen as extensions of the expectation and consensus algorithms from the domain of online scheduling. The problem is especially relevant to the future smart...conference paper 2014

Oliehoek, F.A. (author), Whiteson, S. (author), Spaan, M.T.J. (author)Dec-POMDPs are a powerful framework for planning in multiagent systems, but are provably intractable to solve. This paper proposes a factored forward-sweep policy computation method that tackles the stages of the problem one by one, exploiting weakly coupled structure at each of these stages. An empirical evaluation shows that the loss in...conference paper 2013

Scharpff, J.C.D. (author), Spaan, M.T.J. (author), Volker, L. (author), De Weerdt, M.M. (author)Scheduling of infrastructural maintenance poses a complex multi-agent problem. Commonly a central authority is responsible for the quality and throughput of the infrastructure, while the actual maintenance is performed by multiple self-interested contractors. Not only does the central authority have to (economically) incentivise agents to...conference paper 2013

Elffers, J. (author), Konijnenberg, D. (author), Walraven, E.M.P. (author), Spaan, M.T.J. (author)Several approaches exist to solve Artificial Intelligence planning problems, but little attention has been given to the combination of using landmark knowledge and satisfiability (SAT). Landmark knowledge has been exploited successfully in the heuristics of classical planning. Recently it was also shown that landmark knowledge can improve the...conference paper 2013

Wilmer, D. (author), Klos, T.B. (author), Wilson, M. (author)Temporal scheduling problems occur naturally in many diverse application domains such as manufacturing, transportation, health and education. A scheduling problem arises if we have a set of temporal events (or variables) and some constraints on those events, and we have to find a schedule, which is an assignment of values to the variables that...conference paper 2013

Novak, P. (author), Witteveen, C. (author)In [2] we introduced a theoretical framework for modelling scalable information-aggregation systems. The framework is exposed on the background of a description of METIS, a system prototype aiming at supporting maritime safety and security by facilitating continuous monitoring of vessels in national coastal waters. Among the main problems of...conference paper 2013

Scharpff, J.C.D. (author), Spaan, M.T.J. (author), De Weerdt, M.M. (author)We study the planning of maintenance activities on public infrastructural networks – road networks, Internet, power grids, etc. – in contingent environments such that the negative impact on the network user is minimised. Traditional efforts hereto are mainly of a regulatory nature, whereas we propose charging the service-providers (agents)...conference paper 2012

De Nijs, F. (author), Wilmer, D. (author), Klos, T.B. (author)Voting is a popular way of reaching decisions in multi-agent systems. Weighted voting in particular allows different agents to have varying levels of influence on the decision taken: each agent’s vote carries a weight, and a proposal is accepted if the sum of the weights of the agents in favor of the proposal is at least equal to a given quota....conference paper 2012

Ter Mors, A.W. (author), Witteveen, C. (author)In multi-agent routing, there is a set of mobile agents each with a start location and destination location on a shared infrastructure. An agent wants to reach its destination as quickly as possible, but conflicts with other agents must be avoided. We have previously developed a single-agent route planning algorithm that can find a shortest-time...conference paper 2012

Spaan, M.T.J. (author), Oliehoek, F.A. (author)Multiagent Partially Observable Markov Decision Processes (MPOMDPs) provide a powerful framework for optimal decision making under the assumption of instantaneous communication. We focus on a delayed communication setting (MPOMDP-DC), in which broadcasted information is delayed by at most one time step. In this paper, we show that computation of...conference paper 2012

Noroozian, A. (author), De Weerdt, M.M. (author), Witteveen, C. (author)The fundamental problem with P2P networks is that quality of service depends on altruistic resource sharing by participating peers. Many peers freeride on the generosity of others. Current solutions like sharing ratio enforcement and reputation systems are complex, exploitable, inaccurate or unfair at times. The need to design scalable...conference paper 2012

Ten Thije, O. (author), Planken, L.R. (author), De Weerdt, M.M. (author)Efficient management of temporal constraints is important for temporal planning. During plan development, many solvers employ a heuristic-driven backtracking approach, over the course of which they maintain a so-called Simple Temporal Network (STN) of events and constraints. This paper presents the Vertex-IPPC algorithm, which efficiently...conference paper 2011

Endhoven, L. (author), Klos, T.B. (author), Witteveen, C. (author)Multi-agent planning and scheduling concerns finding a joint plan to achieve some set of common goals with several independent agents each aiming to find a plan or schedule for their part of the goals. To avoid conflicts in these individual plans or schedules decoupling is used. Such a decoupling entails adding local constraints for the agents...conference paper 2011
