[edit] formal section corrected

I corrected the formal section on equilibrium which was badly done. (The dependence of the receiver's action on the sender's was not expressed, leading to a wrong formalisation.) Some minor edits too. The section is not as clear as it could be, but at least not wrong now. I added the possibility of mixed strategies (necessary for equilibrium sometimes), and take credit for the joke about mixed messages!

One point: I am not sure the message/action wording is the best: it seems to imply costless signalling (that different messages are equally costly). CSMR 03:46, 21 November 2005 (UTC)

[edit] Where is Zahavi?

As far as I know, according to Dawkins, A. Zahavi was the first to propose the handicap principle in regards to Birds of Paradise and Thompson's Gazelles. Even if future biologists have expanded upon the theory, Zahavi deserves initial credit for the ideas. (q.v. handicap principle)

If nobody objects, I will update the article accordingly. — MSchmahl… 11:57, 25 December 2007 (UTC)

Yeah, sure, go ahead. Though, in way of some defence of the present state, the article is about signalling games in a fairly strict game theory sense, and I don't think Zahavi's work (as undeniably influential as it is) is as "on point" as Grafen's work. Grafen's work applies game formal game theory, and a signalling game to the problem, along the lines suggested by Zahavi. Cheers, Pete.Hurd (talk) 05:48, 26 December 2007 (UTC)
