[Tex/LaTex] Reduce the line number font size of pseudocode

algorithmicxalgorithmsfontsizepseudocode

I have learned from here on how to reduce the font size in the pseudocode.

The last thing left for me is to reduce the line number font size as well. The following is my MWE, and it seems that \algsetup{linenosize=\tiny} is not working.

\documentclass[a4paper]{article}

\usepackage{algorithmicx}
\usepackage{algorithm} % http://ctan.org/pkg/algorithms
\usepackage[noend]{algpseudocode} % http://ctan.org/pkg/algorithmicx

\begin{document}

\begin{algorithm}
\algsetup{linenosize=\tiny}
\small %\small, \footnotesize, \scriptsize, or \tiny
\caption{a}

\begin{algorithmic}[1]
\Procedure{a}{}
    \While{aa}
        \State aa
    \EndWhile
\EndProcedure
\end{algorithmic}

\label{alg:drs}
\end{algorithm}

\end{document}

You can redefine the \alglinenumber macro:

enter image description here

\documentclass{article}

\usepackage{algorithm} % http://ctan.org/pkg/algorithms
\usepackage[noend]{algpseudocode} % http://ctan.org/pkg/algorithmicx
\algrenewcommand\alglinenumber[1]{\tiny #1:}
\begin{document}

\begin{algorithm}
  \caption{a}\label{alg:drs}
  \begin{algorithmic}[1]
  \Procedure{a}{}
    \While{aa}
      \State aa
    \EndWhile
  \EndProcedure
  \end{algorithmic}
\end{algorithm}

\end{document}

Package algorithmicx provides hooks for use before and after the pseudocode: \ALG@beginalgorithmic and \ALG@endalgorithmic. You can redefine them to suit your needs:

\documentclass{article}

\usepackage{algpseudocode}

\makeatletter
\renewcommand{\ALG@beginalgorithmic}{\small}
\makeatother

\begin{document}

\begin{algorithmic}[1]
  \State $x \gets 42$
\end{algorithmic}

\end{document}

Note that other algorithmicx layouts may redefine the commands. Also note that this doesn't affect line number size, which is controlled by \alglinenumber.

[Tex/LaTex] Reduce pseudocode font size (not global)

The simplest way would be to add \small, \footnotesize, \scriptsize, or \tiny immediately after the beginning of the algorithm environment. This changes the size of everything inside the environment (except for the caption), and nowhere else.

Edited to add: This will apparently leave the size of the line-numbers and of the caption unchanged. In order to change the size of the line-numbers for the algorithm, add the command \algsetup{linenosize=<size>} just inside the algorithm environment, where <size> is again something like \small, \footnotesize, etc. Note that the default is to have line-numbers somewhat smaller than the surrounding text: if you want the appearance to be somewhat similar to algorithms elsewhere in your document, you should also choose a smaller size for the line-numbers than the algorithm body.

I am not sure how best to modify the size of the caption, unfortunately.

Example document.

\documentclass{beamer}
\usepackage{algorithmic,algorithm2e,float}
\begin{document}
\begin{frame}[fragile]
\begin{algorithm}[H]
  \algsetup{linenosize=\tiny}
  \scriptsize
  \begin{algorithmic}[1]
    \FOR{this algorithm only}
      \STATE all of the text in a smaller size of typeface
    \ENDFOR
    \medskip
  \end{algorithmic}
  \caption{an algorithm with smaller typeface}
\end{algorithm}

\bigskip

some text outside of the environment

\bigskip

\begin{algorithm}[H]
  \begin{algorithmic}[1]
    \FOR{all other algorithms}
      \STATE everything normally unless otherwise modified
    \ENDFOR
    \medskip
  \end{algorithmic}
  \caption{an algorithm with normal typeface}
\end{algorithm}
\end{frame}
\end{document}

Result.

Algorithms with different sizes of typeface
