研究人员开发了一种新颖的方法来优化视觉-语言-动作策略，并在MetaFine公开赛中获得第一名。他们的方法包括针对比赛的五个任务分别微调策略，从官方演示和专家程序开始。通过分析局部评估结果并修改演示动作，他们成功解决了抓取、推动和插入任务中的常见失败。这个迭代优化过程通过比较每个指令的检查点以防止回归，使他们的提交MAI取得了96.66的总体分数。 AI

影响这项研究展示了一种优化复杂任务中AI策略的有效方法，有望改进机器人控制和自主系统。

排序理由该集群描述了一篇研究论文，其中详细介绍了一种新颖的视觉-语言-动作策略方法，该方法赢得了比赛。[lever_c_demoted from research: ic=1 ai=1.0]
