"# 第三章 迭代优化\n",
"\n",
"当使用 LLM 构建应用程序时，实践层面上很难*第一次尝试*就成功获得适合最终应用的 Prompt。但这并不重要，只要您有一个好的迭代过程来不断改进您的 Prompt，那么您就能够得到一个适合任务的 Prompt。虽然相比训练机器学习模型，在 Prompt 方面一次成功的几率可能会高一些，但正如上所说， Prompt 是否一次完善并不重要。最重要的是**层层迭代**为您的应用程序找到有效 Prompt 的过程。\n",
"\n",
"因此在本章中，我们将以产品说明书中生成营销文案为例，来展示一些流程框架，并提示您思考如何层层迭代地分析和完善您的 Prompt。\n",
"\n",
"在吴恩达（Andrew Ng，原教程作者）的机器学习课程中展示过一张图表，说明了机器学习开发的流程。通常是先有一个想法，然后再用以下流程实现：编写代码，获取数据，训练模型，获得实验结果。然后您可以查看结果，分析误差与错误，找出适用领域，甚至可以更改您对具体问题的具体思路或解决方法。此后再次更改实现，并运行另一个实验等，反复迭代，最终获得有效的机器学习模型。在编写基于 LLM 的应用程序的 Prompt 时，流程可能非常相似。您产生了关于要完成的任务的想法后，可以尝试编写第一个 Prompt ，注意要满足上一章说过的两个原则：**清晰明确，并且给系统足够的时间思考**。然后您可以运行并查看结果。如果第一次效果不好，那么迭代的过程就是找出为什么指令不够清晰或为什么没有给算法足够的时间思考，以便改进想法、改进 Prompt 等等，循环多次，直到找到适合您的应用程序的 Prompt。\n",
"\n",
"很难有适用于世间万物的所谓“最佳 Prompt ”，更好的方法是找到有效的迭代过程，以便您可以快速地找到一个适合您的应用程序的 Prompt 。\n"
