[edit] minimax theorem

Hi Cretog. My main interest is games on the unit square, and it seems that many very reasonable games have no game value. There does not seem to be an article on games with no value. Actually, I created game value the other day, but this is just a redirect to minimax. We could either create a page games with no value perhaps, or even games on the unit square, neither of which exist. What do you think? Best wishes, Robinh (talk) 12:11, 30 May 2008 (UTC)

Hello again. Just a clarification: Silverman's game has a value (of zero). Did the Silverman's game article lead you to believe that it didn't? If so, it's not very clear and I'll need to rewrite. Best, Robinh (talk) 08:49, 2 June 2008 (UTC)

Hi Robinh (just Robin?). I think I was getting various ideas crossed in my head; Silverman's game does not imply it has no value. The stub there definitely wants some work, though. It doesn't describe any solutions to the game. Also, it might be that it's possible to model it as being on the unit square, but it looks like the current definition is on .

Hi again (yes I am plain Robin but the username was taken)-: Silverman's game seems to refer to more than one game...there seems to be an integer version too... but you're right that the article needs more work. One day I'll actually get round to writing games on the unit square but in the meantime I reckon the minimax article could use a "main article: Von Neumann's minimax theorem" bit. Perhaps such a page would be the place to discuss "counterexamples" (ie games in which the minimax theorem does not apply). Or maybe example of a game with no value would be better. We could use Parthasarathy's example. What do you think? Very best wishes, Robinh (talk) 21:50, 2 June 2008 (UTC)

[edit] Re:

yeah, my bad on that. I'm using an automated anti-vandalism tool and I hit the wrong button. My apologies. Thingg^⊕⊗ 15:18, 5 June 2008 (UTC)

The one I'm using now is called Huggle. It's a very fast and powerful native application tool. (By that I mean it runs on your computer instead of in your browser.) You can click on the link to find out more about it, but I have to tell you, if you do end up getting it, it takes a little bit to get used to. By this I mean, being able to revert and warn with one press of a button can be, well, rather disconcerting at first and you will probably make mistakes. My advice to you is when you first use it, if you have any question as to whether the editor's intentions were bad, don't warn him. (you will probably want to use the "custom edit summary" feature in cases like this too. Huggle can "remember" your edit summaries for each session, so you don't have to type "needs to be cited" or "unsourced change" like 70 times.) Another tool that is very popular is Twinkle, a javascript-based tool that adds a few tabs to the top of the page that make tasks such as speedy-deletion tagging and warnings a lot easier. It also adds some additional functions when you are viewing a page's history. (eg. clicking on "rollback vandal" will rollback the edit and warn the user who made it in one smooth and fast action.) Twinkle isn't quite as fast as Huggle, but it does have the very real advantage of running in your browser, allowing you to do other tasks such as wikifying new articles you may come across, without having to go to a different program. (as is the case with huggle) Another tool I use often is a script written by User:TheJosh and located here. This script adds an extra box in the "toolbar" on the left of the page that provides the functionality of Special:Newpages without having to keep going back to that page. Combined with Twinkle, this script makes new page patrolling almost ridiculously easy because you can leave the box activated, do whatever else you want, (like work on a DYK contribution or something) and be able to take out (maybe that's not a good way to put it, but hey...) bad new pages easily. Also, if you do decide to get the scripts, you may want to copy the code from my javascript page instead of doing the standard install as both scripts have a rather annoying default feature. By default, Twinkle adds all speedied pages to your watchlist. While this can be nice, if you don;t want to see those pages again, it can be really annoying to remove hundreds of deleted pages from your watchlist. Also, the "new pages" script was originally positioned above the search box in the left-toolbar, which can be annoying because you have to scroll waaaay down the page to reach the search box. I tweaked the code to make it show up below the search box, where it's far less of a hassle.

Well, I guess I wrote a sizable novel there, but I hope it will help you out. If you have any questions about these or other tools you may find, please feel free to ask me. Thingg^⊕⊗ 15:41, 5 June 2008 (UTC)

Sorry I didn't get back to you sooner. (missed your comment) What I would recommend if you can't use huggle is to give twinkle a try. It's pretty powerful and it will work on any operating system because it runs in the browser. (Note that it may not work in browsers other than Opera, Safari or Firefox, but since you have a mac, I'm assuming you're using one of these already) All you have to do to install it is go to User:Thingg/monobook.js and copy the top section of code (labeled "SCRIPT: Twinkle") into User:Cretog8/monobook.js. Then, clear your browser's cache by holding down the "ctrl" key and refreshing the page. You will immediately see 7 new "tabs" at the top of all pages to the right of the regular "history", "watch", etc. They include "warn" (brings up a window that allows you to warn vandals), "arv" (report vandals), "csd" (nominate a page for speedy-deletion), "last" (opens the diff of the latest two revisions of the page), "rpp" (request page protection), "xfd" (creates an article for deletion nomination), and "unlink" (tbh, I'm not really sure what this does... *clicks button, wikipedia crashes, runs like heck....* ;) ). In addition, when you view diffs or old revisions of pages, you will see a few additional buttons next to the "undo" (or "rollback", if you have that) that are pretty self-explanatory in function. btw, sorry about the small novel I wrote above as I'm sure that was rather confusing/overwhelming. :o) If you have any other questions, please feel free to ask. Regards. Thingg^⊕⊗ 01:20, 7 June 2008 (UTC)

[edit] My reply to a good question

…but is this section needed at all?

In a better world, certainly not. But those whose reaches exceeds their grasps will insist on presenting that LTV criticism (as illustrated by the history of the article), and in an environment that places a premium on consensus and compromise, the best way of handling that is to allow the presentation and include the response to it. Further, there will be readers who in any event will encounter that criticism, and they will be well served by reading the response. —SlamDiego_←T 23:21, 5 June 2008 (UTC)

[edit] Unemployment

Unfortunitly not... An exam paper I did recently for Economics AS referenced it, that's how I know it's in there soemwhere. I looked breifly but got frustrated, sorry Larklight (talk) 20:48, 9 June 2008 (UTC)

I'll leave the line in, and see if I can find the ref.. If not, I'll hunt out another. Larklight (talk) 19:27, 10 June 2008 (UTC)

[edit] Snowdrift Game

The snowdrift game is just another name for the hawk-dove or chicken game that is used in scientific literature. If you read the news item I sourced then you can figure out the payoff matrix and see that it has the same structure as a hawk-dove game. If you want a more academic source (and have access to Nature publications, actually you only even need access to the abstract) search for "Spatial structure often inhibits the evolution of cooperation in the snowdrift game"(2004) by Christoph Hauert & Michael Doebeli and you will see the following quote:

Two simple games have attracted most attention in theoretical and experimental studies: the Prisoner’s Dilemma and the snowdrift game (also known as the hawk–dove or chicken game).

I can add a little blurb (when I have time) about the analogy used to describe the game (two people stuck in a snowdrift) to the article, but from game-theoretic terms it is just another name for the same game as Hawk-Dove and Chicken.

Cheers --DFRussia (talk) 21:02, 9 June 2008 (UTC)

I know what you mean. The only reason I added that to the Hawk-dove article (or chicken article) was because it took me a little bit of time to find it myself, so I decided to save some time for future readers --DFRussia (talk) 04:30, 10 June 2008 (UTC)

[edit] emailing deleted article?

Hello--You recently deleted the article Swedish auction. I'm not asking for it to be re-instated. I recall seeing somewhere that you could request that the deleted article be emailed to you. I'd be very grateful if you could point me back to that information. Cretog8 (talk) 13:25, 10 June 2008 (UTC)

You can request it either at Wikipedia:Deletion review or by contacting anyone on this list, including me. But you have to set an email address at Special:Preferences first. Stifle (talk) 13:27, 10 June 2008 (UTC)
