TL;DR version: algorithm – float wrapper for algorithms. algorithmic – first algorithm typesetting environment. algorithmicx – second algorithm. The goal is not to entice you to use LaTeX for formatting your algorithms as Algorithm algo:max will find the maximum element in a finite sequence (Slide 14 in. \usepackage[options ]{algorithm2e}. Example. \begin{algorithm}[H] \SetAlgoLined \KwResult{Write here the result }.

The documentation 1 says:. See the example below for details. LaTeX has several packages for typesetting algorithms in form of ” pseudocode “. Post as a guest Name. I am not very familiar with algorithm2e. The algorithm environment provides this and a few other useful features.

Note to users who switched from the old algorithmic package: There are too many options, and it is confusing when to use what. Detailed version algorithm Float wrapper for algorithms. The algorithm environment is meant to address these concerns by providing a floating environment for algorithms.

Your discussion is very clear about why, and whether, to prefer algorithmicx to algorithmicbut doesn’t offer much comparison to algorithm2e. This is not compatible with revtex This will not, however, affect the final layout in the document.


The algorithmicx package provides a number of popular constructs for algorithm designs. The reason for two environments being provided is to allow the user maximum flexibility. The pseudocode is usually put in an algorithm environment.

All the commands are capitalized, e. Float wrapper for algorithms. There are also other layouts, such as:.

algorithm2e – Floating algorithm environment with algorithmic keywords

When placed within the text without being encapsulated in a floating environment algorithmic environments may be split over a page boundary, greatly detracting from their appearance. Home Questions Tags Users Unanswered. I edited my answer to make it clear that it is only my subjective preference.

It provides macros that allow you to create different sorts of key words, thus a set of predefined key words is given.

Sign up using Facebook. The program package provides macros for typesetting algorithms. This layout is incomplete. In the text the n-th parameter is referenced by n. This is the environment in which you write your pseudocode. The algorithmic package is suggested for IEEE journals as it is a part of their default style sheet.

More details are in the manual hosted on the ctan website. Complete documentation is listed at [2]. Unlike algorithmicalgorithm2e provides a relatively huge number of customization options to the algorithm suiting to the needs of various users. For typesetting real code, written in a real programming language, consider the listings package described in Source Code Listings.


It enables you to define custom commands, which is something algorithmic can’t do. See the example for algorithmicxit uses the algpseudocode layout.

You use algorithmicx the same way you use algorithmiconly the syntax and details are slightly different.

Algorithms – Overleaf, Online LaTeX Editor

Augustin 3, 1 12 This package is like algorithmic upgraded. I think they should offer similar functionality, but I prefer the syntax of algorithmicx. Any suggestion will be appreciated. The numbering of algorithms can be influenced by providing algoorithm2e name of the document component within which numbering should be recommenced.

They provide stylistic enhancements over a uniform style i. A lovely, detailed answer!

This is often not desirable, particularly in large documents where numbering according to chapter is more appropriate. You may use only algorithmicx, and define the commands yourself, or you may use one of the predefined command sets.

From Wikibooks, open books for an open world. Aogorithm2e algorithmic package uses a different set of commands than the algorithmicx package.

There are also other layouts, such as: For example, if I use algpseudocodethen I can’t add algorithmic because it is already latec in the algorithm package.
