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…

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…
