我正在使用该algorithm2e包来排版我的算法。我希望能够控制标题编号样式。更具体地说，我希望标题编号用花括号括起来并且是蓝色的，即标题应该说
算法{1} ...
'{1}' 部分为蓝色，而不是
算法1......
从我目前的研究来看，这似乎是
\renewcommand{\thealgocf}{\string{\@arabic{\numexpr\value{algocf}\relax}\string}}
或者
\renewcommand{\thealgocf}{\string{\@arabic\c@algocf\string}}
应该可以解决问题（\{但\}没有奏效，好像转义不起作用：
! TeX capacity exceeded, sorry [input stack size=5000].
\curr@fontshape ->\f@encoding
/\f@family /\f@series /\f@shape
l.337 \end{AlgoFunctionLike}
）
。
\string{产生一个–和\string}一个 ̋ 标记（甚至不能将后者放入逐字引用中......），所以这也不起作用 - 它说
算法 –1̋
我真的不知道任何文本...这里发生了什么，以及（如何）我才能得到我想要的东西？
哦，还有
\renewcommand{\thealgocf}{\textcolor{blue}\string{\@arabic\c@algocf\string}}
给我
\renewcommand{\thealgocf}{\textcolor{blue}\string{\@arabic\c@algocf\string}}
所以颜色似乎也不起作用……
附言：我在文档中没有看到执行此操作的任何选项algorithm2e，有一些选项可以设置数字后的分隔符，还有一些选项可以设置标题的一般字体样式（忘记了命令名称），但没有任何选项可以改变标题数字的样式......
Pps：这是一个小的可行示例（如果您有正确的软件包......）

答案1
使用答案如何改变 algorithm2e 中算法编号和名称的顺序？来帮助指导我。
\documentclass{article}
\usepackage{algorithm2e,xcolor}
\makeatletter
\renewcommand{\fnum@algocf}{\AlCapSty{\algorithmcfname\nobreakspace
\color{blue}\{\AlCapFnt\thealgocf\}}}
\makeatother
\begin{document}
\begin{algorithm}[H]
\SetAlgoLined

\KwResult{how to write algorithm with \LaTeX2e }
initialization\;
\While{not at end of this document}{

\eIf{understand}{

}{
go back to the beginning of current section\;
}
}
\caption{How to write algorithms}
\end{algorithm}
\end{document}
答案2
下面更新计数器表示以用蓝色打印算法编号和括号：
\documentclass{article}
\usepackage{algorithm2e,xcolor}
\renewcommand{\thealgocf}{\textcolor{blue}{\{\arabic{algocf}\}}}
\begin{document}
See Algorithm~\ref{alg:algorithm}.
\begin{algorithm}
\SetAlgoLined
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e }
initialization\;
\While{not at end of this document}{
read current\;
\eIf{understand}{%
go to next section\;
current section becomes this one\;
}{%
go back to the beginning of current section\;
}
}
\caption{How to write algorithms}
\label{alg:algorithm}
\end{algorithm}
\end{document}
由于表示形式已更改，因此自然也会移动到任何\reference 的表示形式。如果您使用自己的引用宏（例如\algoref），那么您可以将其合并为
\newcommand{\algoref}[1]{Algorithm~{\ttfamily\small\ref{#1}}}
