I'm writing my thesis and I have a few algorithms (using algorithm2e) that I want to list in my appendix, but I don't want to start a new page. Also my listoffigures currently creates a section, not a chapter, same for my bibliography.

Therefore I want to do the same for listofalgorithms, but I can't change it correctly. This is how the figure list is changed:

\renewcommand{\listoffigures}{%
  \@cfttocstart
  \par
  \begingroup
    \parindent\z@ \parskip\cftparskip
    \section{\listfigurename}
    \@starttoc{lof}%
  \endgroup
  \@cfttocfinish%
}%

I have tried not changing it from chapter to section, but change the layout of the chapter to section, but I can't get it perfectly, because I can't change the skip distance after the heading.

This is what almost looks right:

\renewcommand\listalgorithmcfname{\thesection\hspace{3mm}List of Algorithms}
\begingroup
    \let\cleardoublepage\relax  % book
    \let\clearpage\relax        % report
    \titleformat{\chapter} [hang] {\Large\bfseries\sffamily} {\thesection} {1em} {}
    \listofalgorithms
\endgroup

I tried suggestions of similar threads, but they use other algorithm packages, so I think the algorithm2e handles things in some different manner.

Any help is appreciated.

Edit: @Werner: I can't tell you why, but it's not working. Maybe it isn't in fact using a chapter, I'm not sure. It starts on a new page and the indent is the same as chapter headers.

This is a MWE:

\documentclass{report}
\usepackage{algorithm2e}
\begin{document}
\begin{algorithm}
    \caption{Algorithm}
\end{algorithm}

\listofalgorithms
\end{document}

I had the same problem and found no solution online, so I opened algorithm2e.sty and dug in. There is actually an undocumented feature to do just that.

I just intended to C-s'd for "chapter" in the whole file until I found something interesting, and I did:

\ifx\l@chapter\undefined\let\algocf@seclistalgo=\section\else\let\algocf@seclistalgo=\chapter\fi
% /!\ this is not part of the solution, it just explains how I found it.

So this means that writing

\makeatletter
\let\l@chapter=\undefined
\makeatother

before calling \usepackage[…]{algorithm2e} will nicely do the trick :).

Another solution is to directly call \@starttoc, knowing that the list of algorithms is toc loa:

\section*{List of Algorithms} % or whatever is preferred
\makeatletter
\@starttoc{loa}
\makeatother

Easiest would be to let \chapter be equivalent to \section:

\begingroup
\let\chapter\section% Make \chapter equivalent to \section
\listofalgorithms
\endgroup

The \chapter update is temporary until \listofalgorithms is complete.
