Wikipedia:WikiProject Game theory

From Wikipedia, the free encyclopedia

Some Wikipedians have formed a project to better organize information in articles related to Game theory. This page and its subpages contain their suggestions; it is hoped that this project will help to focus the efforts of other Wikipedians. If you would like to help, please inquire on the talk page and see the to-do list there.

WikiProject on Game theory


This project is designed to coordinate efforts on Wikipedia pages pertaining to Game theory. This is an interdisciplinary study encompassing Mathematics, Economics, Political science, Psychology, Biology, Computer science and Philosophy. All participants are welcome!

Related WikiProjects and Wikiportals

Since game theory is used by many different disciplines, it is related to many different wikiprojects. Ones with whom we have overlapping interest are:


My name is Miko Filppula and I am the author for "formal precommitment mechanism" also known as prefunding algorithm.

Shubik. M Journal Of Conflict Resolution, Volume 15, Issue 1, Page 110, “If there is no formal mechanism for precommitment, we would need to specify the degree of belief of the other bidders in order to check upon the stability of the market.

According to Dr. Martin Shubik the grandfather of bidding-fee-auction method. Prefunding, formal precommitment mechanism was the original way of doing business in 1971. It was considered commonsense knowledge in 1971 that auction needed to have atleast 2 or more precommitted bidders before the decision to initiate an auction was made.

  • My name is Adam Kalai and I am a professor at Georgia Tech. I am teaching a graduate class in Game Theory. As part of the final, I have asked each student to create/improve a Wikipedia entry on game theory. I hope they have done a good job! 4 May, 2004.
  • I have nominated List of games in game theory for a featured list. Unfortunately, not many people want to review it. Would people involved in this project mind chiming in one way or another? --best, kevin [kzollman][talk] 03:13, 4 October 2006 (UTC)
  • I am working on material for an undergraduate course on decision theory and game theory that develops the math as needed through actual problems encountered in applications throughout the social sciences. When it fills out, it's to be suitable for an audience without a social science background and little math background, up to upper level econ students who use game theory as a primary tool. (My actual class requires one calc class.) Look at the evolving wiki Self Interest and Social Behavior [1] and contribute if you wish. (As a guest, add "— Your Name" at the end of any page that you modify.) Dan Alger 13 June 2006
  • Our article Game theory has now joined Prisoner's dilemma and Rock, Paper, Scissors as a Featured Article. Congrats everyone! --best, kevin [kzollman][talk] 16:10, 6 December 2005 (UTC)
*high five* good work Kevin. Pete.Hurd 16:23, 6 December 2005 (UTC)
Wow! They even beat out Deep Throat and Masturbation! *shakes head in disbelief* today... Pete.Hurd 02:24, 19 October 2005 (UTC)

Tasks has a very nice collection of class notes and a dictionary. If you don't know the area offhand but want to learn this is a great way. Also, most economic publications are distributed on the web long before they ever reach publication. A Google Scholar search will produce lots of papers (although they may be hard to understand in some cases).

Please add a task to this list. If needed explain what you think needs to be done.

Articles to create

Some of these may just need to be redirected.

Articles to modify

  • perfect information The core definition at the top of the page seems inconsistent with the definition. I made a comment on the talk page a few months ago. It states that for perfect information "all players know all moves that have taken place" but this would mean that any card game would be a game of perfect information. Can someone please confirm that this is either right or wrong.Tetron76 (talk) 14:44, 19 February 2011 (UTC)
I have modified the one sentence definition to be consistant with the usage in games, the rest of the article and other sources but did not find a direct source to quote.Tetron76 (talk) 11:27, 23 February 2011 (UTC)

Standardization issues

  • We currently use many different articles when referring to "rational actors" or "behaving rationally". We have a stub perfect rationality, but this might be better served as a redirect for homo economicus. Discuss on the talk page.

Ratings and Assessments

Please help us clean out Category:Unassessed game theory articles and Category:Unrated game theory articles. For assessments see Wikipedia:Version 1.0 Editorial Team/Assessment for a description of what they mean. For the importance ratings, please use the following scale:

  • Top: articles which the general public might be interested in (i.e. game theory, nash equilibrium, and prisoner's dilemma)
  • High: articles which might occur in an undergraduate class (e.g. ultimatum game, best response, subgame perfect equilibrium, etc.)
  • Mid: articles which would occur in any graduate course (e.g. fictitious play, rationalizability, common knowledge)
  • Low: everything else

The ratings are done using parameters to the {{GameTheoryProject}} (which appears on the talk page of relevant articles). Please see its page for instructions.

Are there perhaps statistics available on how often a page is viewed in Wikipedia? That should help us to set priorities.Koczy 17:28, 1 August 2007 (UTC)
Hmmm, I remember Kevin digging up some page listing most visited pages on WP once, and having some GT page high up on the list. But I also remember the list being really stale, and not looking like it was updated. Beyond that I don't know, but it sure does seem like a good idea for prioritizing effort.

Maintaining a complete list would be far too hard and not terribly useful. All of our pages will appear in Category:Game theory. Also, a list of pages that use the above template can be found here. The main article is: Game theory.
