当我在 overleaf 项目的其他部分添加或删除某个段落时，algorithm2e算法主体会间歇性地崩溃，如下面的附图所示。
以下是生成错误的示例代码：

我正在使用 2 列页面，请帮忙。
答案1
（1）删除\SetAlgoLined，以便算法重新出现（在下一页）
（2）重新定义底部规则，添加更多空间以避免与最后一行冲突。
在之前添加\begin{document}
\makeatletter
\def\@algocf@post@ruled{%
\kern8pt%
\hrule width\algocf@ruledwidth height\algoheightrule\relax}%
\makeatother
答案2
这是为您提供的第二种方法。请在屏幕截图后查看我所做的更改。
- 有时，软件包可能会发生冲突，无论是由于设计还是顺序。所以我在这里禁用了所有不需要的软件包。// 相反，当您复制我的方法并开始逐个添加软件包时，您将尽早失败，并且可以避免问题发生。
- 我添加了包
lipsum来创建一些盲文，以便更好地看到页面布局上的效果。 - 我通过 向您的伪代码引入了快捷方式
\newcommand\demo。它接受 1 个参数并将其添加到“p”。看起来\BlankLine您初始代码中的伪代码、-s、返回等的非系统序列可能是造成混淆的一部分。所有这些%都是调用宏时避免出现不必要的空格所必需的。 - 接下来我用
multicols创建 2 列页面布局外部环境algorithm*. - 您的伪代码现在被替换为
\demo{}，这给出了某种标准化。如果我没有multicols里面，它将无法在 1 列中显示所有伪代码。别的和multicols里面只要它在该页面上找到空间，它似乎就可以很好地排版。请记住手册中的警告：它不会跨页面拆分伪代码。
