Please refrain from making unconstructive edits to Wikipedia, as you did at Muhammad ibn Musa al-Khwarizmi. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. - Arjayay (talk) 12:10, 31 January 2018 (UTC)

Welcome!
Hello, and welcome to Wikipedia!

Someone using this IP address, 139.5.254.29, has made edits to Bioluminescence that do not conform to our policies and therefore have been reverted. For more information on this, see Wikipedia's policies on vandalism and limits on acceptable additions. If you'd like to experiment with the syntax, please do so in the sandbox rather than in articles. If you did not do this, you may wish to consider [ getting a username] to avoid confusion with other editors.

You don't have to log in to read or edit pages on Wikipedia, but creating an account is quick, free, requires no personal information, and has many benefits. Without a username, your IP address is used to identify you.

Some good links for newcomers are:
 * Help contents – the main help page.
 * Quick guide – a "cheatsheet" listing the main editing commands.
 * The five pillars of Wikipedia
 * Contributing to Wikipedia
 * Tutorial

Please sign your name on talk pages using four tildes (~&#126;); this will automatically produce your name and a timestamp. If you need help, check out Questions, ask the Help Desk, or place  on your talk page and someone will show up shortly to answer your questions.

Hello, I'm Trilletrollet. I wanted to let you know that one or more of your recent contributions to Dijkstra's algorithm have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks. —Trilletrollet [ Talk | Contribs ] 20:54, 14 June 2020 (UTC)
