Moving caption of the algorithm upwards

Question

I have the following code:

\documentclass{scrbook}


\usepackage[linesnumbered,ruled]{algorithm2e}

\begin{document}

 AAAA

 BBBB

 \begin{algorithm}
 \vspace*{-1cm}
 \caption{My Caption\ldots}
 My Code
 \end{algorithm}

\end{document} 

which does not move the "My Code" part with the caption "My Caption" upwards - but it works for figure environement - any suggestions how this can be done for the algorithms?

NOTE: I know a way of specifying the \vpsace* above the \begin{algorithm} but that won't work if you have a text arround it - it will mess up the text, and not move the algorithm.

Answer 1

You are talking about algorithms that have to stay in place.

So you have two possibilities.

1. Use H as a floating specifier. In this way all the spacing around the algorithm environment is removed.

   \documentclass{scrbook}
   
   \usepackage[linesnumbered,ruled]{algorithm2e}
   
   \begin{document}
   
    AAAA
   
    BBBB
   
    \begin{algorithm}[H]
    \caption{My Caption\ldots}
    My Code
    \end{algorithm}
   
    CCCC
   
   \end{document} 
   

   

2. Use h as a floating specifier and redefine locally the length \intextsep (which represents the distance between floats and text when using h).

   \documentclass{scrbook}
   
   \usepackage[linesnumbered,ruled]{algorithm2e}
   
   \begin{document}
   
    AAAA
   
    BBBB
   
   {\setlength{\intextsep}{0pt}
    \begin{algorithm}[h]
    \caption{My Caption\ldots}
    My Code
    \end{algorithm}
   }
   
    CCCC
   
   \end{document}
