GT in epidemiology

In this edit I partially restored this edit which was reverted in this edit. A review article of the use of tool X in field Y is exactly the correct type of WP:RS to establish a claim of the form "X is a commonly used tool in Y field". I also added in coverage in the popular media for good measure. It certainly looks to me like game theory is used enough in epidemiology to warrant including a section about it in this article. The second half of the material that was reverted, in contrast, is WP:UNDUE focus on a single paper for inclusion in a general encyclopedia article on game theory, and I have not restored that. - Astrophobe (talk) 16:10, 13 September 2021 (UTC)[reply]

Nobel Prizes

"As of 2014, with the Nobel Memorial Prize in Economic Sciences going to game theorist Jean Tirole, eleven game theorists have won the economics Nobel Prize. John Maynard Smith was awarded the Crafoord Prize for his application of evolutionary game theory."

This is pretty out of date. If I'm not mistaken the 2016 and 2020 Nobel Prizes were awarded for work in Game Theory. If someone is able to confirm this understanding, I suggest an edit. — Preceding unsigned comment added by 131.217.255.209 (talk) 23:57, 14 October 2021 (UTC)[reply]

Introduction should mention John Nash

The introduction mentions von Neumann and Morgenstern, but doesn't mention John Nash or Nash equilibria. It probably should, though. Macoroni (talk) 19:37, 20 February 2023 (UTC)[reply]

-== Who is Tina, and why is she wrong ==
-I just DuckDuckGo'd 'Game Theory,' and in the Wikipedia description that shows up on the search page, the very first sentence starts with 'Tina you are wrong theory.' I looked at the history and there are about 5 snapshots where the first sentence with someone calling out this Tina about how wrong she is as the first few words. Just though it was strange and out of place. —[[User:Polynilium|Polynilium]] ([[User talk:Polynilium|talk]]) 23:25, 24 July 2021 (UTC)
-== Quantum game theory ==
-Unless I'm looking the wrong place, the quantum game theory page is a bit bare (to say the least) but in any case, does anyone agree that it would be interesting if added here?
-QGT is one of the more interesting and accessible topics in quantum theory.- 26/10/06 Paul
-== "Perfect information and imperfect information" section ==
-This seems to mix everything up. I'd suggest a rewrite like this, but I don't feel qualified to change it.
-----
-Perfect information and imperfect information
-Main article: Perfect information
-An important subset of sequential games consists of games of perfect information. A game is one of perfect information if all players know the moves previously made by all other players. Thus, only sequential games can be games of perfect information because players in simultaneous games do not know the actions of the other players. Interesting examples of perfect-information games include the ultimatum game and centipede game. Recreational games of perfect information games include chess, go and mancala.
-Perfect information is often confused with complete information, which is a similar concept. See: (provide a link to one place where notion is discussed well...)
-Most games studied in game theory are imperfect-information games. Many card games are games of imperfect information, such as poker or contract bridge. Games of incomplete information can be reduced, however, to games of imperfect information by introducing "moves by nature" (Leyton-Brown & Shoham
-== Potential edit needed ==
-A reader contacted Wikimedia [[:ticket:2020091110005698 ]] challenging the statement that:
-{{talk quote block|Von Neumann's original proof used Brouwer's fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics.    }}
-The reader cited [http://web.math.ucsb.edu/~crandall/math201b/vnminimax.pdf this paper], which does appear to state that the original theorem did not use the concept of fixed point theorems (specifically [[Brouwer fixed-point theorem]]) when he first published in 1928, although he may you used that concept in 1937 (although not in his 1944 book). I've only briefly scanned the paper but it sounds like it makes a decent case.
-Can we discuss whether the source appears solid?
-I'll note that the sentencing question does not appear to be sourced (subsequent sentences have sources but they appear to be supportive of different points).--[[User:Sphilbrick|<span style="color:#000E2F;padding:0 4px;font-family: Copperplate Gothic Light">S Philbrick</span>]][[User talk:Sphilbrick|<span style=";padding:0 4px;color:# 000;font-family: Copperplate Gothic Light">(Talk)</span>]] 15:18, 11 September 2020 (UTC)
