Publisher summary· verbatim

arXiv:2610.30873v1 Announce Type: new Abstract: Mix-policy optimization incorporates off-policy expert data into the reinforcement learning (RL) loop to transcend the capability boundary of on-policy RL. However, existing methods either provide static full-trace guidance that suppresses self-explora
