I noticed some really weird interaction between algorithms2e and the option newfloat of the minted package.

\documentclass{book}

\usepackage{algorithm2e}
\usepackage[newfloat]{minted}


\begin{document}


\listofalgorithms % here the spacing is not correct


\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\end{document}

incorrect spacing

Whereas if I invert the order of the loading of the packages the list of algorithms return to behave normally

\usepackage[newfloat]{minted}
\usepackage{algorithm2e}

correct spacing

I must necessarily load first algorithms2e because I dump my preamble to speed up compilation time since I load a ton of packages for typesetting my book, and I can't dump minted because it seems it doesn't get along with the cache option.

Is there a way to avoid this annoying behaviour?

The problem seems to be an incompatibility between algorithm2e and newfloat package, so it seems to be sufficient to load the newfloat package before the algorithm2e package:

\documentclass{book}

\usepackage{newfloat}
\usepackage{algorithm2e}
\usepackage[newfloat]{minted}


\begin{document}


\listofalgorithms


\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\end{document}

    ...I've send an e-mail to both maintainers, the one from the newfloat package has already answered that she/he will fix it this week-end. –  Feb 27 '21 at 14:36

Some patchwork corrects the problem:

  • Writing algorithms to the <jobname>.lol rather than <jobname>.loa.

  • Update \listofalgorithms to load <jobname>.lol rather than <jobname>.loa.

enter image description here

\documentclass{book}

\usepackage{algorithm2e}
\usepackage[newfloat]{minted}


\makeatletter
% Write algorithm to <jobname>.lol rather than <jobname>.loa
\renewcommand{\algocf@list}{lol}%
% Let \listofalgorithms load <jobname>.lol rather than <jobname>.loa
\patchcmd{\listofalgocfs}% <cmd>
  {loa}% <search>
  {lol}% <replace>
  {}{}% <success><failure>
\makeatother


\begin{document}


\listofalgorithms


\chapter{A chapter}


\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\chapter{A chapter}
\begin{algorithm}\caption{An algorithm}\end{algorithm}
\begin{algorithm}\caption{An algorithm}\end{algorithm}


\end{document}

  • The solution resolve the spacing problems but it raises another one: now I can't distinguish between the list of pseudocode and the list of code, but there is only one list for both type of object. This a patch, not a solution – Emanuele Nardi Feb 27 '21 at 12:22
