algorithm2eline-breaking
Is there any way to add a blank line in algorithm2e?
I have the following document:
\documentclass{article}
\usepackage[linesnumbered]{algorithm2e}% http://ctan.org/pkg/algorithm2e
\begin{document}
\begin{algorithm}
\SetAlgoLined
i = 1 + j\\
% I would like to add a \linebreak here
j = 1 + i\\
\end{algorithm}
\end{document}
This outputs:
I would like to have:
If I add \\ or \linebreak between i = 1 + j\\ and j = 1 + i\\ I get the following error message:
To use the command \captionsetup you must have loaded the caption package...
Anyway, this can be done without it.
First of all, the spacing between the caption and the rest of the text is null because you are preventing the algorithm to float using H as a position specifier. Use h instead, which means "place it here" but keeps the algorithm a floating object (the same as h for figures and tables).
Then you can adjust the spacing between the body of the algorithm and its caption through the command \SetAlCapSkip.
In other words, substituting the line
\begin{algorithm}[H]
with
\begin{algorithm}[h]
and inserting
\SetAlCapSkip{1em}
in the preamble (adjust 1em to your needs) should be what you want.
Complete MWE
\documentclass[a4paper]{article}
\usepackage{blindtext}
\usepackage[linesnumbered,boxed]{algorithm2e}
\SetAlCapSkip{1em}
\SetKwInput{KwInput}{Input}
\SetKwInput{KwOutput}{Output}
\begin{document}
\begin{algorithm}[h]
\SetAlgoLined
\KwInput{Parameters...}
\KwOutput{$\emptyset$}
\If{Condition}
{
Do something \;
}
\caption{Algoritm test...}
\end{algorithm}
\blindtext{}
\begin{figure}[!h]
\caption{Figure test...}
\end{figure}
\blindtext{}
\end{document}
Output
The insertion of an empty item seems to give a better vertical spacing. One can define a myitemize environment that includes this empty item; that will prevent typing it for each description item:
\documentclass{article}
\usepackage{enumitem}
\newenvironment{myitemize}%
{\begin{itemize}\item[]}
{\end{itemize}}
\begin{document}
\begin{description}[style = sameline, leftmargin = 1em]
\item[Animals:]
\begin{itemize}
\item[]
\item Dog
\item Cat
\item Fish
\end{itemize}
\item[Colors:]
\begin{myitemize}
\item Red
\item Green
\item Blue
\end{myitemize}
\end{description}
\end{document}
