Multi-Agent Learning with Cooperation-Driven Optimization Dynamics

The paper proposes a cooperation mechanism for multiple small neural network agents that share predictions during training to reduce model complexity while maintaining performance. By incorporating shared predictions into the loss function, agents influence each other's weight updates through strategies such as voter, majority, and weighted average models. Experiments on standard benchmarks show that several small agents can outperform a single large model, achieving comparable accuracy with fewer parameters and lower computational cost.

Optimization without Future Compromises? Decentralized Coordination via Collective and Reinforcement Learning

The paper introduces Hierarchical Reinforcement and Collective Learning (HRCL), a framework that combines multi‑agent reinforcement learning (MARL) with decentralized coordination. HRCL uses MARL at a high level to generate strategic guidance that limits the decision space for low‑level agents, enabling efficient short‑term coordination while considering long‑term effects. Experiments on synthetic, energy‑management, and drone‑swarm scenarios demonstrate faster convergence and significant reductions in system‑wide and individual costs compared to standalone MARL.

Agentic Autoresearch for Cell-Edge Power Control: Radically Redefining the Researcher's Role

The paper presents an autonomous agent that designs machine learning algorithms for wireless power control, eliminating manual specification of architecture, loss, and training details. Using an autoresearch protocol, the agent iteratively edits a training script, runs experiments, and evaluates changes against a single metric, ultimately achieving 99.5% of a reference solution with vastly reduced inference cost. The agent’s discovered output parameterization matches the exact max‑min‑optimal allocation at the minimum percentile for all trained weights, demonstrating a principled, scalable approach to a complex, NP‑hard problem.

Self-Evolving Multi-Agent Systems via Textual Backpropagation

arXiv:2506. 09046v3 Announce Type: replace-cross Abstract: Leveraging multiple Large Language Models (LLMs) has proven effective for addressing complex, high-dimensional tasks, but current approaches often rely on static, manually engineered multi-agent configurations.
