==GT in epidemiology==
In [https://en.wikipedia.org/enwiki/w/index.php?title=Game_theory&oldid=1044106617 this edit] I partially restored [https://en.wikipedia.org/enwiki/w/index.php?title=Game_theory&oldid=1044093326 this edit] which was reverted in [https://en.wikipedia.org/enwiki/w/index.php?title=Game_theory&oldid=1044095064 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. - [[User:Astrophobe|<span style="color:#ff69b4">'''Astrophobe'''</span>]] ([[User talk:Astrophobe|''talk'']]) 16:10, 13 September 2021 (UTC)


== Quantum game theory ==
== Nobel Prizes ==

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

== The first sentence is not good, and most of the intro is a real struggle ==

I don't know this topic. The whole intro is very hard to follow for the uninitiated. And in the 1st sentence using the phrase "rational decision-makers" without links is so broad and sounds more philosophical than mathematical. Is that the nature of this thing, still very amorphous even after ~60 years?

The 4th sentence would be a better start: "game theory applies to a wide range of behavioral relations, and is now an umbrella term for the science of logical decision making in humans, animals, and computers." But again, those three are very not equally "rational decision-makers" unless that distinction is made way more clear.

I do not know this topic so I can't suggest how to improve it, except to say it direly needs clarity. <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Gatfish|Gatfish]] ([[User talk:Gatfish#top|talk]] • [[Special:Contributions/Gatfish|contribs]]) 04:01, 17 September 2018 (UTC)</small> <!--Autosigned by SineBot-->

: "Logical" and "rational" are both common words, and are synonyms. The precise meaning of the words is explained in the body of the article, as one would expect. Can you try to articulate further what you think is unclear/difficult/whatever about the first paragraph? --[[User:Joel B.

This article needs to refer to (and link to) [[behavioral game theory]]. Behavioral game theory has grown from economics, but also the psychology of judgement and decision-making. It's basically game theory applied to human decision-making that includes considerations for bounded rationality, "natural" preferences, norms, etc. It's now used in everything from anthropology to resource management, hardly restricted to economics and business. In the "General and Applied Uses" > "Economics and Business" subheading of the article, behavioral economics is mentioned, but behavioral game theory is not, even though it's in the titles of several citations. The content itself under that heading has become fairly redundant with the rest of the article, and doesn't have much content specific to business or economics. Of course, since econ, sociology, psych, etc are all social sciences, there's going to be a decent amount of overlap and fuzziness of topics. Still, I'd suggest that
1. "Economics and Business" be reworked with some content that's specific to business and economics.
2. A "Decision-Making and Social Behavior" heading be added that includes some of the content from [[behavioral game theory]], links to it, and refers to it by name. Alternatively, the heading could just be "Behavioral Game Theory."

== Introduction should mention John Nash ==
== Algorithmic Game Theory ==


The introduction mentions von Neumann and Morgenstern, but doesn't mention John Nash or Nash equilibria. It probably should, though. [[User:Macoroni|Macoroni]] ([[User talk:Macoroni|talk]]) 19:37, 20 February 2023 (UTC)
A very hot modern area of game theoretic research. Tied to econ AI and distributed algos. Lots of robust results. Should be mentioned in the article.

GT in epidemiology

[edit]

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

[edit]

"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

[edit]

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]
