arXiv:2604.25972v1 Announce Type: new Abstract: In multi-agent reinforcement learning (MARL), the integration of a communication mechanism, allowing agents to better learn to coordinate their actions and converge on their objectives by sharing information. Based on an interaction graph, a subclass of methods employs graph neural networks (GNNs) to learn the communication, enabling agents to improve their internal representations by enriching them with information exchanged. With growing research, we note a lack of explicit structure and framework to distinguish and classify MARL approaches with communication based on GNNs. Thus, this paper surveys recent works in this field. We propose a generalized GNN-based communication process with the goal of making the underlying concepts behind the methods more obvious and accessible.

Your DzCademia workshop

Check a publication method or promise

A video or journal-finding tool can shortlist titles, not guarantee acceptance. Check identity, scope, author instructions and possible fees at official sources. Do not choose solely on speed promises or one indicator.

A practical exercise

Compare two journals against your research question: fit, article types, instructions and verified terms. Keep unknowns as questions rather than assumptions.
