boxruled 格式算法文本溢出

Question

我有一个算法，它实际上是一串长语句，我希望它放在一个框内，但下面的代码却导致自动换行错误。有人知道为什么吗？

\documentclass[a4paper,10pt]{article}
\usepackage{algorithm2e}
\begin{document}
\RestyleAlgo{boxruled}
\begin{algorithm}
\scriptsize    
\begin{enumerate}
\item This is a long text that overflow the box jjjj jjjjjjjjjjjjj jjjjjjjjjjjj jjjjjjjjjj jjjjjj jjjjj jjjj jjjj jjjjjjj jjjj jjjjjj jjjjjjjjj jjjjj jjjj jjjjj jjjjjjj jjjjjj jjjjjjjjjjj j jjjjjjjj j j jjjjjjjj jjjjj j jj jjjjjjjjjj jjjj jjjj jjjjjjj jjjjjjjj jjjjjjjjj jjjjjjjjj jjjj jjjjjjj jjjjjjjj j jjjj jjjj jjjj j j  jjjjjjj jjj jjjjj jjjjjjjj jj jjjj jjj j jjjjjjj

我试过把它放进去miniboxes，\vbox但没什么用

Answer 1

\addtolength\linewidth{-4ex}已修订。需要在环境内添加该行algorithm。起初，我认为调整是\leftmargini和/或的倍数\labelsep，但在此 MWE 中进一步测试证明这种信念是错误的。相反，对的固定调整\linewidth似乎效果最好。
