Prisoner's Dilemma .......game theory
    #5814021 - 07/02/06 10:50 PM (17 years, 6 months ago)

In game theory, the prisoner's dilemma is a type of non-zero-sum game in which two players try to get rewards from a banker by cooperating with or betraying the other player. In this game, as in all game theory, the only concern of each individual player ("prisoner") is trying to maximize his own advantage, without any concern for the well-being of the other players.

In the prisoner's dilemma, cooperating is strictly dominated by defecting (i.e., betraying one's partner), so that the only possible equilibrium for the game is for all players to defect. In simpler terms, no matter what the other player does, one player will always gain a greater payoff by playing defect. Since in any situation playing defect is more beneficial than cooperating, all rational players will play defect.

I <3 Wiki. Here's the PD entry.

You may also find this recent (June 23, 2006) game-theory study/article interesting.

While I'm at it, check out the infamous Monte Hall problem.

I was reading a mathematical dictionary and came across that.

I have not read it before and found it interesting.

Though I have found many many new and interesting things in that reference book.

the monte hall problem: wtf? they implied that in real life experiments people actually do win more by switching? has anyone tried that? would anyone like to through aim or something?
if this is true it blows my fucking mind and its like some sort of obvious warp in the fabric of reality.

we went over this concept in my managerial economics class during the spring.

great in theory, but i dont think it really has any real world applications.

I love the Monte Hall problem. So basic, so simple once you understand it, but so counterintuitive on first glance. It reminds me to double-check my assumptions about seemingly trivial things.

Yah, we learned about this in my micro class.  Basically a way to "predict" the outcome of certain actions involving supply/output.  Out of the whole damn class that was the only thing i found remotely interesting. :smile:
