This paper is squarely about AI: it proposes an online scheduler for agentic reinforcement learning that uses rollout history and a dual-relation graph to choose training tasks, and reports reaching a target score in 40 steps versus 120 for random selection on Qwen3-8B. The headline efficiency gain is measured on a single model and a few benchmarks, so it should be read as promising evidence rather than a general result. For ML practitioners, the useful idea is treating environment and task data management as a lever for RL training cost, which matters as executable agent environments become expensive to run.
EnvSched: Environment-Aware Scheduling for Rollout-Efficient Agent Reinforcement Learning
arXiv:2610.37609v1 Announce Type: new Abstract: As executable environments for language agents scale, generating and verifying their rollouts becomes increasingly expensive. Under finite rollout budgets, this raises an important question: can data management at the environment level make agentic reinforcement learning (RL) more efficient by organizing, evaluating, and scheduling task instances together with the environments that determine their tools, states, transitions, and verification? To address this question, we introduce EnvSched (Environment-aware Scheduling), an online scheduler that learns from rollout history. EnvSched assigns scheduling value through two complementary modeling choices: exploitation prioritizes tasks likely to provide informative reward differences, while coverage spreads each batch across underobserved environments and interaction patterns. EnvSched organizes environment--task pairs as nodes in a dual-relation graph, with within-environment edges capturing task semantics and shared tool, state, and verifier structure, and cross-environment edges capturing abstract execution and reward topology. By propagating historical rollout statistics along both edge types, it predicts within-task reward variance. These predictions guide a scheduler that allocates each batch to tasks with high predicted reward variance and underobserved environments and tasks. Environment quotas and a similarity penalty further limit concentration and redundancy, yielding informative and diverse batches without additional pilot rollouts. In RL on Qwen3-8B, EnvSched achieves an average score of 48.81 across BFCL-v3, tau-Bench, and ACEBench-Agent after 40 training steps, exceeding the highest score attained by random task selection after 120 steps. It also improves downstream performance across model sizes at the same training budget.
