Value of Information-Enhanced Exploration in Bootstrapped DQN
Stergios Plataniotis, Charilaos Akasiadis, Georgios Chalkiadakis
Efficient exploration in deep reinforcement learning remains a fundamental challenge, especially in environments characterized by high-dimensional states and sparse rewards. Tradit…
Conditional Max-Sum for Asynchronous Multiagent Decision Making
Dimitrios Troullinos, Georgios Chalkiadakis, Ioannis Papamichail +1
In this paper we present a novel approach for multiagent decision making in dynamic environments based on Factor Graphs and the Max-Sum algorithm, considering asynchronous variable…
A Novel Multiagent Flexibility Aggregation Framework
Stavros Orfanoudakis, Georgios Chalkiadakis
The increasing number of Distributed Energy Resources (DERs) in the emerging Smart Grid, has created an imminent need for intelligent multiagent frameworks able to utilize these as…
Optimising Long-Term Outcomes using Real-World Fluent Objectives: An Application to Football
Ryan Beal, Georgios Chalkiadakis, Timothy J. Norman +1
In this paper, we present a novel approach for optimising long-term tactical and strategic decision-making in football (soccer) by encapsulating events in a league environment acro…
Optimising Game Tactics for Football
Ryan Beal, Georgios Chalkiadakis, Timothy J. Norman +1
In this paper we present a novel approach to optimise tactical and strategic decision making in football (soccer). We model the game of football as a multi-stage game which is made…
Overlapping Coalition Formation via Probabilistic Topic Modeling
Michalis Mamakos, Georgios Chalkiadakis
Research in cooperative games often assumes that agents know the coalitional values with certainty, and that they can belong to one coalition only. By contrast, this work assumes t…
Cooperative Games with Overlapping Coalitions: Charting the Tractability Frontier
Yair Zick, Georgios Chalkiadakis, Edith Elkind +1
In many multiagent scenarios, agents distribute resources, such as time or energy, among several tasks. Having completed their tasks and generated profits, task payoffs must be div…
Cooperative Games with Overlapping Coalitions
Georgios Chalkiadakis, Edith Elkind, Evangelos Markakis +2
In the usual models of cooperative game theory, the outcome of a coalition formation process is either the grand coalition or a coalition structure that consists of disjoint coalit…
