Breaking the Performance Ceiling in Reinforcement Learning requires Inference Strategies

NeurIPS 2025oral

Reinforcement learning (RL) systems have countless applications, from energy-grid management to protein design. However, such real-world scenarios are often extremely difficult, combinatorial in nature, and require complex coordination between multiple agents. This level of complexity can cause even…

Memory-Enhanced Neural Solvers for Routing Problems

NeurIPS 2025spotlight

Routing Problems are central to many real-world applications, yet remain challenging due to their (NP-)hard nature. Amongst existing approaches, heuristics often offer the best trade-off between quality and scalability, making them suitable for industrial use. While Reinforcement Learning (RL) offer…

Oryx: a Scalable Sequence Model for Many-Agent Coordination in Offline MARL

NeurIPS 2025poster

A key challenge in offline multi-agent reinforcement learning (MARL) is achieving effective many-agent multi-step coordination in complex environments. In this work, we propose Oryx, a novel algorithm for offline cooperative MARL to directly address this challenge. Oryx adapts the recently proposed…

Combinatorial Optimization with Policy Adaptation using Latent Space Search

NeurIPS 2023poster

Combinatorial Optimization underpins many real-world applications and yet, designing performant algorithms to solve these complex, typically NP-hard, problems remains a significant research challenge. Reinforcement Learning (RL) provides a versatile framework for designing heuristics across a broad…

Neuroevolution is a Competitive Alternative to Reinforcement Learning for Skill Discovery

ICLR 2023top-25%

Deep Reinforcement Learning (RL) has emerged as a powerful paradigm for training neural policies to solve complex control tasks. However, these policies tend to be overfit to the exact specifications of the task and environment they were trained on, and thus do not perform well when conditions devia…
