Cleveref+Algorithmic: Apparent Change in Label Generation between pdfTeX, Version 3.141592653-2.6-1.40.25 and 3.141592653-2.6-1.40.26

The combination of the cleveref and algorithmic packages is a powerful tool for creating high-quality documents that include algorithms and pseudocode. However, users of these packages have reported an apparent change in label generation between pdfTeX, Version 3.141592653-2.6-1.40.25 and 3.141592653-2.6-1.40.26. In this article, we will explore this issue and provide a minimal working example (MWE) to demonstrate the problem.

The cleveref package is a powerful tool for creating high-quality references in LaTeX documents. It allows users to create references to equations, sections, and other elements in a document using a simple and intuitive syntax. The algorithmic package, on the other hand, is a tool for creating algorithms and pseudocode in LaTeX documents. It provides a set of commands and environments for creating algorithms, including the algorithmic environment, which is used to create algorithms, and the algorithm environment, which is used to create algorithms with a specific layout.

Users of the cleveref and algorithmic packages have reported an apparent change in label generation between pdfTeX, Version 3.141592653-2.6-1.40.25 and 3.141592653-2.6-1.40.26. Specifically, they have reported that the labels generated by the cleveref package are different between the two versions of pdfTeX. This change in label generation can cause problems for users who rely on the cleveref package to create high-quality references in their documents.

To demonstrate the problem, we will create a minimal working example (MWE) that uses the cleveref and algorithmic packages to create an algorithm with labeled lines. The MWE is as follows:

\documentclass{article}
\usepackage{algpseudocode}
\usepackage{cleveref}
\begin{document}
\section{Algorithm}
\begin{algorithmic}
\State  $x \leftarrow 0$ 
\State  $y \leftarrow 0$ 
\State  $z \leftarrow 0$ 
\State \textbf{while}  $x &lt; 10$  \textbf{do}
\State   \textbf{if}  $y &lt; 5$  \textbf{then}
\State      $y \leftarrow y + 1$ 
\State   \textbf{else}
\State      $z \leftarrow z + 1$ 
\State   \textbf{end if}
\State    $x \leftarrow x + 1$ 
\State \textbf{end while}
\end{algorithmic}
\crefline1 is the first line of the algorithm.
\crefline2 is the second line of the algorithm.
\crefline3 is the third line of the algorithm.
\crefline4 is the fourth line of the algorithm.
\crefline5 is the fifth line of the algorithm.
\crefline6 is the sixth line of the algorithm.
\crefline7 is the seventh line of the algorithm.
\crefline8 is the eighth line of the algorithm.
\crefline9 is the ninth line of the algorithm.
\crefline10 is the tenth line of the algorithm.
\end{document}

When we compile this MWE using pdfTeX, Version 3.141592653-2.6-1.40.25, we get the following output:

Algorithm 1: $x \leftarrow 0$ 2: $y \leftarrow 0$ 3: $z \leftarrow 0$ 4: \textbfwhile} $x < 10$ \textbf{do} 5 \textbf{if $y < 5$ \textbfthen} 6 $y \leftarrow y + 1$ 7: \textbf{else 8: $z \leftarrow z + 1$ 9: \textbfend if} 10 $x \leftarrow x + 1$ 11: \textbf{end while

line:1 is the first line of the algorithm. line:2 is the second line of the algorithm. line:3 is the third line of the algorithm. line:4 is the fourth line of the algorithm. line:5 is the fifth line of the algorithm. line:6 is the sixth line of the algorithm. line:7 is the seventh line of the algorithm. line:8 is the eighth line of the algorithm. line:9 is the ninth line of the algorithm. line:10 is the tenth line of the algorithm.

However, when we compile this MWE using pdfTeX, Version 3.141592653-2.6-1.40.26, we get the following output:

As we can see, the labels generated by the cleveref package are different between the two versions of pdfTeX.

In conclusion, the apparent change in label generation between pdfTeX, Version 3.141592653-2.6-1.40.25 and 3.141592653-2.6-1.40.26 is a problem that affects users of the cleveref and algorithmic packages. This change in label generation can cause problems for users who rely on the cleveref package to create high-quality references in their documents. We hope that this article has provided a useful example of the problem and has helped to raise awareness of this issue.
