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This is pretty out of date.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]

-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?

-== "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

-== Removal of Economics Sidebar ==
-I think that the economics sidebar should be removed, since Game Theory doesn't seem to be primarily concerned with Economics.  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Get Learnt|Get Learnt]] ([[User talk:Get Learnt#top|talk]] • [[Special:Contributions/Get Learnt|contribs]]) 05:33, 30 May 2018 (UTC)</small> <!--Autosigned by SineBot-->
-Yes I would be in agreement with you, there are much more approproate imagges. Fro exampel a symbolic depiction of the a network or the proziners Dilema.

-== ''(Non-)determinstic'': in terminology? ==
-I hesitate to add this, as I am not familiar with the usual terminology, but surely there is an important distinction, worth adding under ''[[Game_theory#Game_types|Game types]]'', between games whose course is entirely determined by the decisions of the players and those influenced by an element of chance. (This is of course not the same as [[Determinacy]] or a [[determined game]].) If added, it would also belong in [[Glossary of game theory]].

+== Nobel Prizes ==
-== The first sentence is not good, and most of the intro is a real struggle ==
+"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."
-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?
+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.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/131.217.255.209|131.217.255.209]] ([[User talk:131.217.255.209#top|talk]]) 23:57, 14 October 2021 (UTC)</small> <!--Autosigned by SineBot-->
-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.
+== Introduction should mention John Nash ==
-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.  In the field they have precise meanings, which are explained later in the article.  I am totally sympathetic to the idea that Wikipedia articles on mathematical subjects are often not accessible enough, but surely one must try to read past the first paragraph to have a convincing story about whether or not it is accessible?  --[[User:Joel B.
