# Horizontal spacing in caption in algorithm2e

In algorithm2e, how can I shift the caption to the left? There is a small space that I need to remove.

Here is my code:

\documentclass[letterpaper]{article}
\usepackage[linesnumbered,ruled]{algorithm2e}

\begin{document}

\begin{algorithm}[t]
Initialize
\\
Do stuff ...
\caption{Example sdfkjdshf ksdjhf dskjfhssdkjfhds kfsjh 1kjh kjh kjh d}
\label{alg:example}
\end{algorithm}

\end{document}


UPDATE Even if there is space for some characters, the caption goes on a new line. Why? How can I fix that?

• Don't mix the use of algorithm2e with algpseudocode. One or the other.

• Why is it a problem? It does not give me any error and I use it for \Call. Sep 17, 2015 at 20:20
• You can write your own algorithm2e-like \Call. They each handle the display of content differently.

• Ok, did not know that there can be conflicts. Fixed :) Sep 17, 2015 at 20:42
• You need an inner loop without an outer one, this is illogical. I know of no language in which you can work in inner loop skipping the outer one. Sep 17, 2015 at 20:57

\documentclass[letterpaper]{article}
\usepackage[linesnumbered,ruled]{algorithm2e}
\begin{document}

\SetAlCapHSkip{0em}
\begin{algorithm}[t]
Initialize
\\
Do stuff ...
\parbox{\linewidth}{\caption{Example caption long enough caption to see how it wraps at page borders.}}
\label{alg:example}
\end{algorithm}

\end{document}


You can add the command \SetAlCapHSkip{<length>} to control that space before the caption. Here, I just reset it to zero by \SetAlCapHSkip{0em}. You can choose whatever value you feel nice.

In case you need to adjust the indentation of the numbers also, you can use the command \DecMargin{<length>} to decrease their margin by the value <length>.

Update

The caption package is not actually necessary here. For your edited part of the question, you can solve the width issue by using a \parbox (of width equal to the total \linewidth) for the caption as follows:

\parbox{\linewidth}{\caption{<...>}}

• Many thanks! But what if cannot use the caption package? Sep 17, 2015 at 23:34
• And I also added a new small question. I would really appreciate if you can help me :) Sep 18, 2015 at 0:30
• @Simon Please see my update. Sep 18, 2015 at 1:32
