Thank you. I mean, I know I sort of said it to you, but you're right. It's logarithmic, right?
但你们是正确的，是对数级的,它有这样的效率是因为他每次能把问题减半？
-
So in fact, what does that suggest about the order of growth here? What is the complexity of this? Yeah. Logarithmic. Why?
复杂度是多少？,对的，对数级的么？，为什么呢？,学生：对数级的？

What does a logarithmic running time look like?
这个对数函数是怎样的？

So, this is several months and this logarithmic scale on the Y-axis represents antibody concentration.
这是在几个月内,这里使用的是对数刻度,Y轴代表的是抗体的浓度
-
It's a good sign that this is logarithmic, and I'm going to come back in a second to why logs are a great thing.
为什么对数级复杂度是个好事情，让我们再来看一个算法,噢，抱歉是让我们再来看两个算法。
-
Logarithmic. This matters. This matters a lot.
你们要记住并注意这个特征。
-
We also saw a logarithmic algorithm.
我们也看过对数算法。
-
Perhaps more importantly, how to recognize a kind of algorithm based on its properties and know what class it belongs to. This is a hint. If you like, leaning towards the next quiz, that you oughta be able to say that looks like a logarithmic algorithm because it's got a particular property. That looks like an n log n algorithm because it has a particular property.
也许更重要的是,如何根据一个算法的特点将其辨别出来,并且知道它属于哪一类算法,这是一个提示，就对于接下来的测验来说,如果你喜欢你可以说它看起来像一个对数算法,因为它有一个特定的性质,那个看起来像一个n，log，n的算法,因为它有一个特定的性质。
