Now. You might look at that and say, well that's just a lot like what we had over here Right? We had some additive constant plus a simpler version of the same problem reduced in size by 1.
现在你可能会看着这个说,这很像我们以前做过的,对不对?我们用一些附加的常量,加上问题的另外一个规模缩小了1的,简化版本来代替这个问题本身。
OK, that's not so bad. Moving a stack of size 2 if I want to go there, I need to put this one temporarily over here so I can move the bottom one before I move it over.
好,并不那么难,移动上面两个圆盘的话2,我需要把最小的盘子,临时先放到多余的柱子上来,这样才能在把它移过来之前,把最底下的盘子放到目标柱子上。

The size of that is v^2 over R.
它的大小是 v^2 / R
the abuse is, you know, it's not quite right, it depends upon whether it's all ready, but you can see in either case, after 12 steps, 2 runs through this and down to a problem size b over 2.
在12步以后,两轮过后,这个问题的范围b被缩小了一倍,这为什么很不错呢?,这意味着再来12步。
If I want to move this stack here, I'm going to take a stack of size n minus 1 move it to the spare spot, now I can move the base disk over, and then I'm going to move that stack of size n minus 1 to there. That's literally what I did, OK?
如果我想移动这些圆盘,我先把从n-1个圆盘1,移动到多余的柱子上去,这样我就能把最底下的圆盘放到这儿了,然后再把从n-1个圆盘放到这儿来,这就是确切的我怎么做的对不对?
