Well this isn't going to do very much for me as we'll see

正如我们所见这并不是很多
because I'll get 2 + 0 tomorrow

因为下一次博弈的收益是2+0
because we know I'm playing defect tomorrow

因为大家都知道我下一次会用背叛策略
2 + 0 tomorrow, - 1 + 0 tomorrow, 3 + 0 tomorrow, 3 + 0 tomorrow

收益分别是2+0, -1+0, 3+0, 3+0
- 1 + 0 tomorrow, and 0 + 0 tomorrow, 0 + 0 tomorrow.

-1+0和0+0, 0+0
So just as we did with the war of attrition game two weeks ago

就像我们前两个星期做的消耗战博弈一样
we can put in the payoffs from tomorrow

我们可以加入下一次博弈的收益
we can roll back those equilibrium payoffs to today

把这些均衡收益回推到现在的博弈
it's just in this particular exercise it's rather a boring thing

只是在这个练习里实在是无聊
because we're just adding 0 to everything.

因为我们在每一项收益里都加了0
When I add 0 to everything,

当我给每一项加上0时
I then just cancel out the zeros and I'm back where I started,

我只是抵消了0然后又回到了开始的博弈
