[Tex/LaTex] Missing end statement in algorithm2e environment

algorithm2e

I used \SetKwProg{myproc}{Procedure}{}{} for starting my pseudo-code with Procedure keyword. But its end statement (the last end in pseudo-code) is not appear in the result pdf. So how can i bring it?

\documentclass[10pt,a4paper]{article}
\usepackage[algo2e]{algorithm2e}

\begin{document}

\IncMargin{1em}
\begin{algorithm2e}[H]
\SetKwFunction{proc}{BuildEBTM}%
\SetKwProg{myproc}{Procedure}{}{}
\SetKwInOut{Input}{input}
\SetKwInOut{Output}{output}
\SetKwFunction{connect}{Connect}
\SetKwData{ce}{ce}
\myproc{\proc{}}{
    \Input{A Process $M$}
    \Output{A Process $EM$}
    \BlankLine
    \ForEach{FlowElement $e$ in $M$}{
        \ForEach{Converter $c$ in $Converters$}{
            \If{$c$ accepts $e$}{
                \ce $\leftarrow$ $c$ converts $e$\;
                \connect($EM$,\ce)\;
            }               
        }
    }
}
\caption{my procedure}
\label{my_procedure}
\end{algorithm2e}
\DecMargin{1em}

\end{document}

The result pdf without last end statement:

Best Answer

According to the documentation on CTAN, the last argument of the \SetKwProg command sets the end text. So get that 'end', the builder for the \myproc command should be

\SetKwProg{myproc}{Procedure}{}{end}

The problem is caused by the relsize package (internally loaded by algorithm2e); the former package is incompatible with the AMS document classes; processing the following document:

\documentclass[12pt]{amsart}
\usepackage{relsize}
\begin{document}
test
\end{document}

produces the exact problem mentioned in the question; the process ends with many warnings and the obtained .pdf is the following:

To prevent this from happening, load the algorithm2e package with the norelsize package option, as in:

\usepackage[norelsize]{algorithm2e}

A complete example:

\documentclass[12pt]{amsart}
\usepackage[norelsize]{algorithm2e}

\begin{document}

\begin{algorithm}[H]
\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}
\end{algorithm}

\end{document}

Perhaps the algorithmicx package could be of interest for you (it provides many possibilities to customize the layout of algorithms) to be used instead of algorithm2e.

[Tex/LaTex] Remove “end” in algorithm2e

This is entirely covered in the algorithm2e documentation (section 10.4 if-then-else macros), and is provided by \lIf (short for line If):

enter image description here

\documentclass{article}
\usepackage{algorithm2e}
\newcommand{\True}{\textbf{true}}
\begin{document}
\begin{algorithm}[H]
  \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\;
    }
    \lIf{condition}{\Return{} \True}
  }
  \caption{How to write algorithms}
\end{algorithm}

\end{document}
