d) 增量{++} :½ N(N+1) to N^2.,coursera上ppt的½ N (N − 1) to N (N − 1)是错的 Mathematical Models, slide 28, 30, 32. Number of increments should be½ N(N+1) to N^2. (参见coursera 课程勘误表Resources--Errata) 当i == 0 时,i 先进行递增,j 也递增了 N-1 ...
Algorithms: Design and Analysis, Part 1 这门课的第二个编程问题。 这一道题要求对比在快排算法中,使用不同的pivot策略所带来的总的比较数的不同。这道题我试了5次才使得所有的结果正确,前边错误主要的问题在于partition算法和课上讲的不一致。 题目要求的选取pivot的方法共分三种:1)选取第一个;2)选取最后一...
可以看出这样也比原来立方的级别好很多,更好的数量级,更好的性能表现。 Theory of Algorithms 而实际情况会比上面的例子复杂些,事实是对不同的输入,算法会有不同的性能表现。像二分查找,其实最好的情况是常数级别的。所以针对不同的输入,我们经常需要从不同的角度来分析问题,可分为最好、最差和平均三种类型。但...
