R^2Orch: Recursive self-play orchestration (arXiv:2610.22740v1)
The paper introduces R^2Orch, a Recursive Self-Play Orchestration paradigm that trains an orchestrator with an inner self-play loop and an outer loop that withdraws skills based on a new Recursive Learnability objective. The method adds a Skill Withdrawal mechanism and a Proposer that selects tasks; experiments on twelve datasets (question answering, math, code, interactive tasks) report consistent improvements over baselines.
