Some [[Wikipedia:Wikipedians|Wikipedian]]s have formed a [[Wikipedia:WikiProject|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 [[{{NAMESPACE}} talk:{{PAGENAME}}|talk page]] and see the [[Wikipedia:to-do list|to-do list]] there.

==Scope==

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 Portals==

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

''Please contribute to [[Talk:Battle of the sexes (game theory)#BoS = Bach or Stravinsky?|the discussion on whether Battle of the Sexes (BoS) should be changed to Bach or Stravinsky]]. There are comments regarding depiction of gender stereotypes and spousal abuse in the current presentation. There is no academic difference between the two presentations.

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 [[WP:FL|featured list]].  Unfortunately, not many people want to review it.  Would people involved in this project mind [[Wikipedia:Featured list candidates/List of games in game theory|chiming in]] one way or another?  --''best, kevin'' <b>[</b>[[User:Kzollman|kzollman]]<b>][</b>[[User talk:Kzollman|talk]]<b>]</b> 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''' [http://junction.brynmawr.edu/display/danalger] and contribute if you wish. (As a guest, add "— Your Name" at the end of any page that you modify.) [[User:gametheoryman|Dan Alger]] 13 June 2006
* Our article [[Game theory]] has now joined [[Prisoner's dilemma]] and [[Rock, Paper, Scissors]] as a [[WP:FA|Featured Article]].  Congrats everyone! --best, kevin <b>[</b>[[User:Kzollman|kzollman]]<b>][</b>[[User talk:Kzollman|talk]]<b>]</b> 16:10, 6 December 2005 (UTC)

==Tasks==

[http://www.gametheory.net GameTheory.net] 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 [http://scholar.google.com 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 modify===
<!-- Place new stuff at the top -->
* [[Complete information]] needs better references, and probably has a lot of text that needs to be re-written. The article may even need to be deleted altogether if it is found to be redundant with (or not distinctly different from) [[Perfect information]].
* [[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.[[User:Tetron76|Tetron76]] ([[User talk: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.[[User:Tetron76|Tetron76]] ([[User talk:Tetron76|talk]]) 11:27, 23 February 2011 (UTC)
* The [[list of games in game theory]] article needs to address the [[cake cutting problem]].
* It has been proposed that [[Battle of the sexes (game theory)]] be merged into [[coordination game]], please chime in at [[Talk:Coordination game]].  --''best, kevin'' <b>[</b>[[User:Kzollman|kzollman]]<b>][</b>[[User talk:Kzollman|talk]]<b>]</b> 05:11, 29 June 2006 (UTC)
* [[User:Pete.Hurd|Pete]] and [[User:Kzollman|I]] have been nominating several of our articles for [[WP:GA|good article status]].  Some of them are being turned down, receiving some good suggestions in the process.  If you're interested in improving an article that is close, please try one of these articles (see its associated talk page for suggestions). --''best, kevin'' <b>[</b>[[User:Kzollman|kzollman]]<b>][</b>[[User talk:Kzollman|talk]]<b>]</b> 19:43, 13 June 2006 (UTC)
**{{article|best response}}: is it worth trying again?  should I re-nom this article for GA? [[User:Pete.Hurd|Pete.Hurd]] 17:04, 22 August 2006 (UTC)
**{{article|extensive form game}}
* The [[Wikipedia:Version_1.0_Editorial_Team/WPEconBusiness#Wikipedia:WikiProject_Game_theory|WP 1.0 Editorial Team]] is concerned about the lack of references in some of our articles.  Many of these articles don't have references because there is no natural references -- the facts are common knowledge amongst game theorists (e.g. [[Extensive form game]]).  However, I understand their concern.  We should add textbook references were applicable to these articles and try to do this with new articles.  I suggest we start maintaining a list of articles that need to be references at [[Wikipedia:WikiProject Game theory/References needed]]. --best, kevin  <span style="color:#BBBBBB;">·</span><span style="color:#666666;">·</span>·<small>[[User:Kzollman|Kzollman]] | [[User Talk:Kzollman|Talk]]</small>·<span style="color:#666666;">·</span><span style="color:#BBBBBB;">·</span> 17:04, 8 November 2005 (UTC)  
*[[Evolutionarily stable strategy]] - the example needs some fixing.  In a perfect world, it would use a simple bimatrix game and illustrate the difference between an ESS and a [[Nash equilibrium]].  I think the [[game of chicken]] / hawk-dove game will do, with the mixing/pure ESSes and [[uncorrelated asymmetry]] effects on Nash/ESSs explained, but perhaps a simpler example can be found . The sex ratio example that is there now ought to be fixed (once & for all) and moved to the [[sex ratio]] entry.
*Help needed on [[cooperative game]]s. Anyone remembers Banzaff's solution? Also, how to make Shapley's solution readable? Examples of cooperation in boardgames will be appretiated, too. [[User:Mousomer|mousomer]] 00:01, 17 October 2005 (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 {{[[Template:GameTheoryProject|GameTheoryProject]]<!--
-->{{#if:{{{2|}}}|&#124;{{{2}}}}}<!--
-->{{#if:{{{3|}}}|&#124;{{{3}}}}}<!--

-->}} (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.[[User:Koczy|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.
