Unlike previous LLM-based approaches limited to discrete actions, PRoC3S handles complex, real-world constraints by separating planning into LLM program generation and constraint satisfaction phases. The system iteratively refines plans using feedback from a physics simulator, achieving high success rates in simulated and real-world robotic manipulation tasks. The paper compares PRoC3S against existing baselines, demonstrating its superior efficiency and robustness in handling continuous parameters and diverse constraints expressed in natural language. Future work focuses on improving the constraint satisfaction methods and incorporating visual reasoning.这篇研究论文介绍了 PRoC3S，一种新颖的机器人规划系统，利用大型语言模型（LLMs）生成并执行涉及连续参数的计划。与以往基于 LLM 的方法仅限于离散动作不同，PRoC3S 通过将规划分为 LLM 程序生成和约束满足两个阶段来处理复杂的真实世界约束。该系统利用物理模拟器的反馈迭代优化计划，在仿真和实际的机器人操作任务中取得了高成功率。论文将 PRoC3S 与现有基线方法进行了对比，展示了其在处理连续参数和以自然语言表达的多样化约束时的优越效率和鲁棒性。未来的研究将重点改进约束满足方法并结合视觉推理能力。原文链接：https://arxiv.org/abs/2406.05572

Using Trust Games, the study finds that LLMs, particularly GPT-4, exhibit trust behaviors aligning significantly with human patterns, demonstrating a high degree of behavioral alignment. The research also explores biases in LLM trust behavior, the impact of external manipulation and reasoning strategies on LLM trust, and the implications for human simulation, agent cooperation, and human-agent collaboration. The findings suggest considerable potential for using LLMs to simulate human social interactions but also highlight potential limitations and risks. The study provides a framework for understanding the analogy between LLMs and human behavior beyond value alignment.这篇研究论文探讨了大型语言模型（LLMs）是否能够模拟人类的信任行为。通过使用信任游戏，该研究发现，LLMs，特别是GPT-4，表现出与人类行为模式显著一致的信任行为，展现了高度的行为一致性。研究还探讨了LLMs信任行为中的偏见、外部操控和推理策略对LLMs信任行为的影响，以及这些对人类模拟、智能体合作和人机协作的意义。研究结果表明，LLMs在模拟人类社会互动方面具有相当大的潜力，同时也指出了其可能的局限性和风险。该研究为理解LLMs与人类行为之间的类比关系提供了一个超越价值对齐的框架。原文链接：https://arxiv.org/abs/2402.04559
