Latex使用minipage调整伪代码宽度踩的坑

在Latex中使用algorithm2e进行伪代码编写的时候，伪代码的默认宽度是页面的宽度，在单栏的文本中，长短差别较大的伪代码会显得非常不美观，如下图所示。

此时，需要通过调整伪代码的宽度来美化伪代码的观感。经过搜索，发现了数个使用了minipage对伪代码的宽度进行调整教程：
Latex写的伪代码宽度调整
关于伪代码和表格宽度的设置 Latex
LaTeX 算法环境宽度调整 Algorithm Width

我于是直接将双栏文档中的伪代码latex源码copy到minipage域内，示例如下：

\begin{minipage}{0.5\linewidth}
\begin{algorithm}
  \caption{This is a pseudo code example}
  \LinesNumbered
  \KwIn{This is a pseudo code example}
  \KwOut{This is a pseudo code example}
  \While{true}{
      This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. \\
      This is a pseudo code example. \\
      This is a pseudo code example. \\
      This is a pseudo code example. \\
  }
\end{algorithm}
\end{minipage}

13
14

结果出现了如下报错：

最后通过仔细阅读LaTeX 算法环境宽度调整 Algorithm Width的内容发现，原来是少了一个环境位置H，再加入center语句进行居中后的正确Latex源码如下所示：

\begin{center}
\begin{minipage}{0.5\linewidth}
\begin{algorithm}[H]
  \caption{This is a pseudo code example}
  \LinesNumbered
  \KwIn{This is a pseudo code example}
  \KwOut{This is a pseudo code example}
  \While{true}{
      This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. This is a pseudo code example. \\
      This is a pseudo code example. \\
      This is a pseudo code example. \\
      This is a pseudo code example. \\
  }
\end{algorithm}
\end{minipage}
\end{center}

调整宽度前后效果对比如图
