Vertical space after caption

I am writing an algorithm in the figure environment, and when I write caption, it does not appear decently. Rather, it appears too close to the textbox.

Here is a MWE

\documentclass[10pt,emptycopyrightspace]{ewsn-proc}
\usepackage{amsmath,balance,amssymb,amsfonts,complexity,filecontents,graphicx,pgfplots,textcomp,tikz,tikz-3dplot}
\usepackage[most]{tcolorbox}
\usepackage[noend]{algpseudocode}
\usepackage{algorithm}
\usepackage[sort,nocompress]{cite}
\begin{document}
\begin{figure}[htbp]
\fbox{\begin{minipage}{\columnwidth}
\textsc{SomeAlgorithm}
\begin{algorithmic}[1]

\State Do this
\State Do that
\If{You cannot do this or that}
\State Do something else
\EndIf
\While{You are not successful}
\State Work hard
\EndWhile
\end{algorithmic}  \end{minipage}}

\caption{Some algorithm}
\end{figure}
\end{document}


And this is the output:

The caption is too close to the border of the figure. I tried to give some space with \vspace{...} but it does not work.

How can write captions such that they are a bit far away from the figure?

• in article class it compiles ok without this problem. This means that your class or your class options causes this problem. Please provide a way to access somewhere your class. (Also edit your post to add the first backslash above the code at your documentcalss command) – koleygr Sep 7 '17 at 22:11
• Look into the caption - this lets you customise basically everything of a caption. – user36296 Sep 7 '17 at 22:13

Just add the caption package, which sets more decent spacing between caption and float. This being said, I don't see why you don't use the algorithm environment, with style boxed. You'll also have a separate numbering for algorithms. As I don't have your class installed I use article with option twocolumn:

\documentclass[10pt, twocolumn]{article}%,emptycopyrightspace]{ewsn-proc}%
\usepackage{amsmath, amssymb, amsfonts, balance, filecontents, graphicx, complexity, pgfplots, textcomp, tikz, tikz-3dplot}%,
\usepackage[most]{tcolorbox}
\usepackage[noend]{algpseudocode}
\usepackage[boxed]{algorithm}
\usepackage{caption}
\captionsetup[boxed]{skip=6pt}
\usepackage{lipsum}
\usepackage[sort,nocompress]{cite}

\begin{document}

\lipsum[11]
\begin{figure}[htbp]
\fbox{\begin{minipage}{\columnwidth}
\textsc{SomeAlgorithm}
\begin{algorithmic}[1]

\State Do this
\State Do that
\If{You cannot do this or that}
\State Do something else
\EndIf
\While{You are not successful}
\State Work hard
\EndWhile
\end{algorithmic} \end{minipage}}

\caption{Some algorithm}
\end{figure}
\lipsum[11]
\begin{algorithm}[htbp]%
\textsc{Some Algorithm}
\begin{algorithmic}%[1]
\State Do this
\State Do that
\If{You cannot do this or that}
\State Do something else
\EndIf
\While{You are not successful}
\State Work hard
\EndWhile
\end{algorithmic}
\caption{Some algorithm}
\end{algorithm}
\lipsum[6-10]

\end{document}
