书籍文档中的算法标题大小减少

我需要在我的算法中将字幕大小减小到脚本大小。我找不到合适的答案。这是我的代码的 MW E：

\documentclass[12pt,a4paper]{book}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{caption}
\begin{algorithm}
\caption{GenerateGraph(schema)}
\scriptsize
\begin{algorithmic}[1]
....
\end{algorithmic}
\end{algorithm}

另外，有没有办法减少数字大小？（它们看起来比文本大）我已将我的算法附在下面。非常感谢您的帮助。

这个问题已经有一个很好的答案了，我不清楚为什么它被删除了...:-( 不过，既然它已被删除，我会尝试自己回答：

使用caption包可以设置标题的字体大小\captionsetup{font=scriptsize}：

\documentclass[12pt,a4paper]{book}

\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{caption}

\begin{document}

\begin{algorithm}
\captionsetup{font=scriptsize} % set size of caption font
\caption{Euclid’s algorithm}
\scriptsize                    % set size of algorithm itself
\begin{algorithmic}[1] % example taken from the algorithmicx documentation
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
  \State $r\gets a\bmod b$
  \While{$r\not=0$}\Comment{We have the answer if r is 0}
    \State $a\gets b$
    \State $b\gets r$
    \State $r\gets a\bmod b$
  \EndWhile
  \State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\end{algorithm}

\begin{algorithm}
\caption{Euclid’s algorithm}
\begin{algorithmic}[1] % example taken from the algorithmicx documentation
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
  \State $r\gets a\bmod b$
  \While{$r\not=0$}\Comment{We have the answer if r is 0}
    \State $a\gets b$
    \State $b\gets r$
    \State $r\gets a\bmod b$
  \EndWhile
  \State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\end{algorithm}

\end{document}

（由于\captionsetup{font=scriptsize}应用于 内部algorithm，因此它仅影响当前algorithm。）

没有caption包时，宏\floatc@ruled用于排版算法标题，因此可以修补它以应用于\scriptsize以下算法（仅限）：

\documentclass[12pt,a4paper]{book}

\usepackage{algorithm}
\usepackage{algpseudocode}

\makeatletter
\newcommand\setalgorithmcaptionfont[1]{%
  \let\my@floatc@ruled\floatc@ruled          % save \floatc@ruled
  \def\floatc@ruled{%
    \global\let\floatc@ruled\my@floatc@ruled % restore \floatc@ruled
    #1\floatc@ruled}}
\makeatother

\begin{document}

\setalgorithmcaptionfont{\scriptsize} % set size of next algorithm caption font
\begin{algorithm}
\caption{Euclid’s algorithm}
\scriptsize                    % set size of algorithm itself
\begin{algorithmic}[1] % example taken from the algorithmicx documentation
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
  \State $r\gets a\bmod b$
  \While{$r\not=0$}\Comment{We have the answer if r is 0}
    \State $a\gets b$
    \State $b\gets r$
    \State $r\gets a\bmod b$
  \EndWhile
  \State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\end{algorithm}

\begin{algorithm}
\caption{Euclid’s algorithm}
\begin{algorithmic}[1] % example taken from the algorithmicx documentation
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
  \State $r\gets a\bmod b$
  \While{$r\not=0$}\Comment{We have the answer if r is 0}
    \State $a\gets b$
    \State $b\gets r$
    \State $r\gets a\bmod b$
  \EndWhile
  \State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\end{algorithm}

\end{document}
