中文简介: | "我叫埃里克·德梅你应该叫我艾瑞克欢迎回到 6.0 46。这是第2课。今天, 我们将基本上填写第1课的一些更数学的基础。所以, 讲座 1, 我们只是有点勉强得到了我们的脚湿了一些分析的算法, 插入排序和合并。我们需要一些工具。我们有一个关于渐近和忘记常量的大想法, 只是看一下前置术语。所以, 今天, 我们要开发渐近表示法, 以便我们在数学上知道这一点。我们最后还得到了合并的递归, 合并的运行时间, 所以我们需要看看如何解决递归。我们今天将做这两件事。问题?是的, 我会说得更大声。谢谢。很好...... "/ |
课程简介: | //"My name is Erik Demaine. You should call me Erik. Welcome back to 6.046. This is Lecture 2. And today we are going to essentially fill in some of the more mathematical underpinnings of Lecture 1. So, Lecture 1, we just sort of barely got our feet wet with some analysis of algorithms, insertion sort and mergesort. And we needed a couple of tools. We had this big idea of asymptotics and forgetting about constants, just looking at the lead term. And so, today, we're going to develop asymptotic notation so that we know that mathematically. And we also ended up with a recurrence with mergesort, the running time of mergesort, so we need to see how to solve recurrences. And we will do those two things today. Question? Yes, I will speak louder. Thanks. Good..."// |
