Currently, when I want to add some algorithm's pseudocode to my LaTeX export, I have to manually write LaTeX:

** Pixel-Flipping: A Technique to Assess Faithfulness
- Pixel-flipping is a quantitative, empirical method to evaluate the faithfulness of explanations.
- It involves iteratively removing input features based on their importance and observing the impact on model predictions.
  - The resulting curves are called /Deletion Curves/.

#+BEGIN_SRC latex
\begin{algorithm}[H]

\caption{Pixel-Flipping}

\begin{algorithmic}
\STATE $pfcurve = []$
\FOR{$p$ in $argsort(-R)$}

\STATE $x \leftarrow x - \{x_p\}$ (remove pixel $p$ from the image)
\STATE $pfcurve.append(f(x))$

\ENDFOR
\RETURN $pfcurve$
\end{algorithmic}
\end{algorithm}
#+END_SRC

Is there a way I can just write the pseudocode in an org-babel source block (e.g., in Python), and it gets converted to a LaTeX algorithm block automatically?

  • Did you look at setting the :results to latex? Does that do what you want?

Be sure you have the line #+LaTeX_HEADER: \usepackage{algorithm2e} at the beginning of your .org file and then remove the lines #+BEGIN_SRC latex and #+END_SRC from your algorithm snippet. Then exporting to LaTeX/pdf will give you this: enter image description here

  • The snippet I provided in the question is LaTeX already. I want to write in a Python-like language and export as LaTeX. I guess it's not possible.
