Before refrigerators were invented, the next best thing was an ice box.

VOA: special.2009.11.30

Once I deleted all the strategies that were never a best response and just focused on that little box of strategies that survived, the picture looked exactly the same as it did before, albeit it blown up and the numbers changed.

一旦剔除了非最佳对策的策略,仔细研究剩下的策略时,图像还和以前看起来是一样的,尽管坐标改变了,图像放大了

I've deleted all the strategies that were best, that are never best responses for Player I and all the strategies that are never best responses for Player II, and what I've got left is that little box.

我剔除了所有策略,所有非参与人I最佳对策的策略,还有非参与人II最佳对策的策略,最后只剩下了这个小方格
