Researchers have developed PaperScout, an autonomous agent designed to improve academic paper search by treating it as a sequential decision-making process. Unlike traditional methods that rely on fixed workflows, PaperScout dynamically adapts its search and expansion strategies based on the ongoing retrieval context. To address training challenges in such multi-turn agentic tasks, the team introduced Proximal Sequence Policy Optimization (PSPO), a novel method that aligns optimization with the agent's interaction sequence. Experiments show PaperScout outperforms existing retrieval and reinforcement learning baselines in recall and relevance. AI
