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 }.

It provides macros that allow you to create different sorts of key words, thus a set of predefined key words is given. This is the environment in which you write your pseudocode. Yes, that is right. The pseudocode is usually put in an algorithm environment.

Algorithms – Overleaf, Online LaTeX Editor

From Wikibooks, open books for an open world. Post as a guest Name. This is just a layout for algorithmicx which tries to be as simillar as possible to algorithmic. They provide stylistic enhancements over a uniform style i.

I think they should offer similar functionality, but I prefer ,atex syntax of algorithmicx. Like algorithmicthis package is also not compatible with Revtex The reason for two environments being provided is to allow the user maximum flexibility. LaTeX has several packages for typesetting algorithms in form of ” pseudocode “.

Note to users who switched from the old algorithmic package: Is that because you are less familiar with it, because it is well known to be inferior, or something else?


There are also other layouts, such as: The algorithmic package is suggested for IEEE journals as it is a part of their default style sheet. Augustin 3, 1 12 This will not, however, affect the final layout in the document. By using this site, you agree to the Terms slgorithm2e Use and Privacy Policy.

Complete documentation is listed at [2]. This is an example taken from the manual official manual, p.

So if you don’t want to write your crazy custom commands, you will be fine with algorithmic. I am not very familiar with algorithm2e. You can use the old algorithms with the algcompatible layout, but please use the algpseudocode layout for new algorithms.

algorithm2e – Floating algorithm environment with algorithmic keywords

Even if you load algorithmicx I understand you still have to load algorithm too? Home Questions Tags Users Unanswered. See the example below for details. Unlike algorithmicalgorithm2e provides a relatively huge number of customization options to the algorithm suiting to the needs of various users.

This is often not desirable, particularly in large documents where numbering according to chapter lahex more appropriate. Most commands are similar to the algorithmicx equivalents, but with different capitalization.

See the example for algorithmicxit uses the algpseudocode layout. I am confused about the packages for writing simple “algorithms”. Retrieved from ” laetx You can also change the typography of the keywords. Sign up using Facebook. There is 1 pending change awaiting review. Sign up using Email and Password. Float wrapper for algorithms.


Your discussion is very clear about why, and whether, to prefer algorithmicx to algorithmicbut doesn’t offer much comparison to algorithm2e. This package is like algorithmic upgraded. Algorithm2e is an environment for writing algorithms in LaTeX2e. You may use only algorithmicx, and define the commands yourself, or you may use one of the predefined command sets Example: I use algorithmicx with algpseudocode since they are superior to algorithmic.

Email Required, but never shown. I edited my answer to make it clear that it is only my subjective preference.


It enables you to define custom commands, which is something algorithmic can’t do. The program package provides macros for typesetting algorithms.

More advanced customization and other constructions are described in the algorithmicx manual: You use algorithmicx the same way you use algorithmicltaex the syntax and details are slightly different.

The algorithm environment provides this and a few other useful features.
