VOA: standard.2009.12.25
It wasn't the fact that they were running that time and they say "Oops! We are over the speed limit!
不是因为跑到那个时间,就说“不好,超过速度极限了!
Let's suppose n is 1000, and we're running at nanosecond speed.
假入我们一秒钟运算十亿次,我们已经看过了对数级,线性增长的。
If you're a doctor and you've got a patient who's running away from you at the speed of light, you'll know what to do.
如果你是个医生,你的一个病人以光速逃跑了,你就知道该怎么办了
If I'm running at nanosecond speed, 1000 n, the size of the problem, whatever it is, is 1000, and I've got a log algorithm, it takes 10 nanoseconds to complete.
如果这个问题的规模,也就是n,是,如果这个问题是对数级的,这将会占据10纳秒的时间,你一眨眼的时间。
