How to write If not(condition)

Question

I am trying to write the algorithm shown in the picture in latex but I cannot know which package suitable for it either algorithm, or algorithm2e. Beside that the flow itself, I do not know how to write the condition "if not".

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. — Community, Sep 20 '22 at 06:48
For an overview of algorithm packages see: algorithm, algorithmic, algorithmicx, algorithm2e, algpseudocode = confused. — dexteritas, Sep 20 '22 at 11:02
it is a good overview, but I still cannot figure it out how to write "if not (condition)"! — Yaaqob Saad, Sep 21 '22 at 06:42
Even if you couldn't figure out how to write "if not (condition)", it would have been nice for you to create a MWE with the rest of it. And for the question to be answerable, you would have needed to pick from one of the 5 algorithm packages mentioned. — Teepeemm, Nov 09 '23 at 19:19

I don't know much about this, but you could try

\documentclass[]{article}
\usepackage[ruled]{algorithm2e} % remove [ruled] if you like
\SetKwIF{IfNot}{ElseIfNot}{}{if not}{then}{else if not}{}{}
\begin{document}
\begin{algorithm}
  \caption{An algorithm}
  \lIfNot{...}{...}
  \lIf{...}{...}
\uIfNot{A}{
    ...;
  }\uElseIf{B}{
    ...;
  }\uElseIfNot{B}{
    ...;
  }\Else{
    ...;
  }
\end{algorithm}
\end{document}

Given the multitude of algorithm packages, it would be nice if you would show a short, but compilable document in your answer so people can see which packages etc. you use. – samcarter_is_at_topanswers.xyz Nov 08 '23 at 12:58

Sorry, I misread the question as being specific about algorithm2e. I have now edited my answer to be compilable. It's only requirement is the algorithm2e package – user615536 Nov 09 '23 at 17:36
