Modify algorithm to compatible with IEEEtran

algorithmicgraphicsieeetran

IEEEtran suggests do not use the algorithm floating environment. So I have been trying to mimic the original look of algorithm without success.

Here is my algorithm with algorithm floating environment:

\begin{algorithm}[!t]
 \caption{my algorithm}
 \label{alg: alg}
\begin{algorithmic}[1]
 \renewcommand{\algorithmicrequire}{\textbf{Input:}}
 \renewcommand{\algorithmicensure}{\textbf{Output:}}
 \REQUIRE input
 \ENSURE  output \\
\STATE $i\gets 10$
\IF {$i\geq 5$} 
  \STATE $i\gets i-1$
\ELSE
  \IF {$i\leq 3$}
    \STATE $i\gets i+2$
  \ENDIF
\ENDIF 
\end{algorithmic}
 \end{algorithm}

However, if I use figure enviroment, the algorithm looks so ugly.

\begin{figure}[!t]
 \caption{my algorithm}
 \label{alg: alg}
\begin{algorithmic}[1]
 \renewcommand{\algorithmicrequire}{\textbf{Input:}}
 \renewcommand{\algorithmicensure}{\textbf{Output:}}
 \REQUIRE input
 \ENSURE  output \\
\STATE $i\gets 10$
\IF {$i\geq 5$} 
  \STATE $i\gets i-1$
\ELSE
  \IF {$i\leq 3$}
    \STATE $i\gets i+2$
  \ENDIF
\ENDIF 
\end{algorithmic}
 \end{figure}

How can I generate the algorithm like the first one without violiting IEEEtran rules?

Here is the full code:

\documentclass[journal]{IEEEtran}
\usepackage{amsmath,amsfonts}
\usepackage{algorithmic}
\usepackage{algorithm}
\usepackage{array}
\usepackage[]{subfig}
\usepackage{stfloats}
\usepackage{graphicx}
\usepackage{mathtools}
\usepackage{newtxtext, newtxmath}
\usepackage{lipsum}




\begin{document}

\lipsum[1]
\begin{algorithm}[!t]
 \caption{my algorithm}
 \label{alg: alg}
\begin{algorithmic}[1]
 \renewcommand{\algorithmicrequire}{\textbf{Input:}}
 \renewcommand{\algorithmicensure}{\textbf{Output:}}
 \REQUIRE input
 \ENSURE  output \\
\STATE $i\gets 10$
\IF {$i\geq 5$} 
  \STATE $i\gets i-1$
\ELSE
  \IF {$i\leq 3$}
    \STATE $i\gets i+2$
  \ENDIF
\ENDIF 
\end{algorithmic}
 \end{algorithm}
 
\lipsum[2]
\begin{figure}[!t]
 \caption{my algorithm}
 \label{alg: alg}
\begin{algorithmic}[1]
 \renewcommand{\algorithmicrequire}{\textbf{Input:}}
 \renewcommand{\algorithmicensure}{\textbf{Output:}}
 \REQUIRE input
 \ENSURE  output \\
\STATE $i\gets 10$
\IF {$i\geq 5$} 
  \STATE $i\gets i-1$
\ELSE
  \IF {$i\leq 3$}
    \STATE $i\gets i+2$
  \ENDIF
\ENDIF 
\end{algorithmic}
 \end{figure}
\end{document}

Best Answer

algorithm package was not allowed in the past. This is stated as follows in the file bare_adv.tex.

Do NOT use the algorithm floating environment provided by algorithm.sty (by the same authors) or algorithm2e.sty (by Christophe Fiorio) as the IEEE does not use dedicated algorithm float types and packages that provide these will not provide correct IEEE style captions.

Now IEEE allows algorithm package. You can choose any journal template in IEEE-Template Selector. For example, IEEE Internet of Things Journal template, we open the bare_jrnl_new_sample4.tex in it. You can see the following code.

\documentclass[lettersize,journal]{IEEEtran}
\usepackage{amsmath,amsfonts}
\usepackage{algorithmic}
\usepackage{algorithm}
...
\begin{algorithm}[H]
\caption{Weighted Tanimoto ELM.}\label{alg:alg1}
\begin{algorithmic}
\STATE
\STATE {\textsc{TRAIN}}$(\mathbf{X} \mathbf{T})$
\STATE \hspace{0.5cm}$ \textbf{select randomly } W \subset \mathbf{X}  $
\STATE \hspace{0.5cm}$ N_\mathbf{t} \gets | \{ i : \mathbf{t}_i = \mathbf{t} \} | $ \textbf{ for } $ \mathbf{t}= -1,+1 $
\STATE \hspace{0.5cm}$ B_i \gets \sqrt{ \textsc{max}(N_{-1},N_{+1}) / N_{\mathbf{t}_i} } $ \textbf{ for } $ i = 1,...,N $
\STATE \hspace{0.5cm}$ \hat{\mathbf{H}} \gets  B \cdot (\mathbf{X}^T\textbf{W})/( \mathbb{1}\mathbf{X} + \mathbb{1}\textbf{W} - \mathbf{X}^T\textbf{W} ) $
\STATE \hspace{0.5cm}$ \beta \gets \left ( I/C + \hat{\mathbf{H}}^T\hat{\mathbf{H}} \right )^{-1}(\hat{\mathbf{H}}^T B\cdot \mathbf{T})  $
\STATE \hspace{0.5cm}\textbf{return}  $\textbf{W},  \beta $
\STATE
\STATE {\textsc{PREDICT}}$(\mathbf{X} )$
\STATE \hspace{0.5cm}$ \mathbf{H} \gets  (\mathbf{X}^T\textbf{W} )/( \mathbb{1}\mathbf{X}  + \mathbb{1}\textbf{W}- \mathbf{X}^T\textbf{W}  ) $
\STATE \hspace{0.5cm}\textbf{return}  $\textsc{sign}( \mathbf{H} \beta )$
\end{algorithmic}
\label{alg1}
\end{algorithm}
...
\end{document}

So, there is an example for you. I suggest you use algpseudocodex package. And I adjusted some styles according to what my editor modified. I hope it will be helpful to you.

\documentclass{IEEEtran}
\usepackage[commentColor=black]{algpseudocodex}
\tikzset{algpxIndentLine/.style={draw=black}}
\algrenewcommand{\alglinenumber}[1]{\bfseries\footnotesize #1}
\algrenewcommand{\textproc}{}
\algrenewcommand{\algorithmicrequire}{\textbf{Input:}}
\algrenewcommand{\algorithmicensure}{\textbf{Output:}}
\usepackage{algorithm}
\floatplacement{algorithm}{tbp}
\makeatletter
\newcommand{\algorithmname}{\ALG@name}
\renewcommand{\floatc@ruled}[2]{{\@fs@cfont #1:} #2\par}
\makeatother
\begin{document}
\begin{algorithm}
\caption{Algorithm}
\label{alg}
\begin{algorithmic}[1]
\Require input
\Ensure  output
\State $i\gets 10$
\If {$i\geq 5$}
    \State $i\gets i-1$
\ElsIf{$i\leq 3$}
    \State $i\gets i+2$
\EndIf
\end{algorithmic}
\end{algorithm}
\end{document}

Default style

\documentclass{IEEEtran}
\usepackage{algpseudocodex}
\algrenewcommand{\algorithmicrequire}{\textbf{Input:}}
\algrenewcommand{\algorithmicensure}{\textbf{Output:}}
\usepackage{algorithm}
\begin{document}
\begin{algorithm}
\caption{Algorithm}
\label{alg}
\begin{algorithmic}[1]
\Require input
\Ensure  output
\State $i\gets 10$
\If {$i\geq 5$}
    \State $i\gets i-1$
\ElsIf{$i\leq 3$}
    \State $i\gets i+2$
\EndIf
\end{algorithmic}
\end{algorithm}
\end{document}

[Tex/LaTex] Algorithm and IEEEtran

The IEEEtran's documentation suggests:

B. Algorithms

IEEE publications use the figure environment to contain algorithms that are not to be a part of the main text flow. Peter Williams’ and Rogerio Brito’s algorithmic.sty package [24] or Szász János’ algorithmicx.sty package [25] (the latter is designed to be more customizable than the former) may be of help in producing algorithm-like structures (although authors are of course free to use whatever LaTeX commands they are most comfortable with in this regard). However, do not use the floating algorithm environment of algorithm.sty (also by Williams and Brito) or algorithm2e.sty (by Christophe Fiorio) as the only floating structures IEEE uses are figures and tables. Furthermore, IEEEtran will not be in control of the (non-IEEE) caption style produced by the algorithm.sty or algorithm2e.sty float environments.

So, as suggested, do not use the algorithm floating environment; you can wrap your algorithm inside a figure (or figure*) environment (if a caption is required and the captions are to be IEEEtran compliant) and use the algorithmicx package ; something like this:

\documentclass{IEEEtran}
\usepackage{algpseudocode}

\begin{document}

\begin{figure}
\begin{algorithmic}[1]
\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\label{euclidendwhile}
\State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\caption{Euclid's algorithm}\label{euclid}
\end{figure}

\end{document}

If no caption is required, then simply don't use the figure environment.

[Tex/LaTex] Two figures side by side with text wrapping

You have to carefully adjust the dimensions of your image and the number of lines the wrap figure will extend ( for example [10] in \begin{wrapfigure}[10]{r}{5.5cm}).

An example:

\documentclass{article}
\usepackage{graphicx,wrapfig,lipsum}
%------------------------------------------
\begin{document}
This is where the table goes with text wrapping around it. You may
embed tabular environment inside wraptable environment and customize as you like.
%------------------------------------------
\begin{wrapfigure}[10]{r}{5.5cm}
\rule{5.5cm}{7.1cm}
\caption{A wrapped figure}\label{wrap-fig:1}
\end{wrapfigure}
%------------------------------------------
This is where the table goes with text wrapping around it. You may
embed tabular environment inside wraptable environment and customize as you like. This is where the table goes with text wrapping around it. You may
