新的PMCTS算法实现了原则性的并行推理扩展
研究人员开发了粒子蒙特卡洛树搜索（PMCTS），这是一种新颖的算法，旨在解决蒙特卡洛树搜索（MCTS）在神经网络评估中并行化所面临的挑战。与传统的顺序MCTS不同，PMCTS提供了一种原则性的方法来实现并行推理时间扩展，同时保持正式的策略改进保证。实证结果表明，PMCTS能够有效地随着并行计算能力的提升而扩展，并在多个领域超越现有的基于启发式的方法。

LiteCoOp框架赋能LLM协作以实现编译器优化
研究人员开发了LiteCoOp，一个旨在通过使多个大型语言模型（LLMs）协同工作来优化编译器性能的新颖框架。这种方法允许异构LLMs通过优化搜索树本身共享进展，避免了复杂的代理协调需求。通过利用共享的蒙特卡洛树搜索（MCTS）结构，LiteCoOp确保一个模型取得的进展能够告知其他模型的后续决策，从而缩短编译时间和API成本。
