So, here's an example of a third reason from

这就是我们上一讲第三个理由的
what we already mentioned last time,

一个不错的例证
but a third reason why we might be interested in Nash Equilibria.

这便是我们学习纳什均衡的第三个原因
There're certain circumstances in which play converges in the natural sense

有些情况下博弈会朝着趋向于
not in a formal sense but in a natural sense to an equilibrium.

一个均衡的方向自然发展
With the exception of a few dogged people who want to pay for my lunch,

除了那些有钱原意请我吃午餐的老顽固
almost everyone else was converging to an equilibrium.

其他参与人都会趋向于一个均衡
So play converged fairly rapidly to the Nash Equilibrium.

博弈的结果会不断趋近于纳什均衡
But we discussed there were two Nash Equilibria in this game.;

但我们讨论得出此博弈有两个纳什均衡
Is one of these Nash Equilibria, ignoring me for a second,

这两个纳什均衡当中
is one of these Nash Equilibria better than the other?

有哪一个优于另一个吗
Yeah, clearly the "Everyone investing" nash Equilibrium is the better one,

很显然大家都投资这个纳什均衡较好
