进化规划（EP）是数值优化最重要的方法之一。其主要技术是突变与自适应机制的结合。过去几年关于EP的研究主要集中在如何提高不同概率分布的突变效率，很少涉及自适应机制有时不起作用的问题，而只是简单地遵循最初的建议。到目前为止，还没有实验结果表明为什么这是一个问题。本文首先对自适应机制的行为进行了初步分析，然后提出了实验证据来说明其自适应能力为何值得怀疑。
Evolutionary programming (EP) is one of the most important methods for numerical optimization. Its main technique is the combination of mutations and the self-adaption mechanism. In the past years, studies on EP focused on how to improve the efficiency of mutations with different probability distributions, and few of them touched on the question that the self-adaption mechanism did not work sometimes, but simply followed the original suggestion. So far, no experimental results have shown why this is a question. This paper firstly gives a primary analysis on the behavior of the self-adaption mechanism, and then presents experimental evidences to show why its adaptive ability is doubtful.
