Adaptive Sandbox Evolution: Dynamic Environment Complexity for Agentic LLM Training

TL;DR: What if the ALE’s sandbox (ROCK) could change its own complexity in real-time, based on how well ROME is performing—making things harder or easier so the agent keeps learning? The experiment could involve a self-adjusting environment that automatically introduces new tools, constraints, or distractions as the agent masters existing challenges.

Research Question: Can dynamically evolving the training environment’s complexity improve the long-term adaptability and robustness of agentic LLMs?

Hypothesis: Agents trained in sandboxes that adaptively scale challenge levels in response to agent proficiency will generalize better to unseen tasks and exhibit greater robustness to distribution shifts.

Experiment Plan: - Setup: Modify ROCK to support automatic environment scaling (e.g., more tools, increasing task difficulty, introducing noise).

• Training: Train ROME variants with static vs. adaptive environments.
• Data: Use a suite of tasks with varying complexity; log agent performance and adaptation speed.
• Evaluation: Test agents on a set of held-out, high-complexity tasks and measure performance drop-off relative to training complexity.
• Expected Outcome: Agents from adaptive sandboxes will show less performance degradation on novel or more complex tasks.
