2. binary search (sorted array) 给定查找对象,array,以及最大最小的范围;将查找对象与middle作比较,进而改变最大最小的范围,然后调用递归 时间复杂度的计算要考虑最坏的情况,本题中最坏的情况类比一条面包每天吃一半几天吃完的问题,时间复杂度为log以2为底n的对数 O(log2n)可以直接写成O(log n),与底数...
"Mathematical Analysis of Algorithms" 由著名的计算机科学家 Donald Knuth 于 1971 年发表。 这篇文章主要引入两个具体的算法问题来展现算法效率分析的典型方法。 Rearranging data without using auxiliary memory space. 不使用额外的存储空间的排序算法(原地排序)。 Finding the element of rank t when n elements...
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...

This is the first installment of the ALGORITHMICS COLUMN dedicated toAnalysis of Algorithms(AofA) that sometimes goes under the nameAverage-Case Analysis of AlgorithmsorMathematical Analysis of Algorithms. The area of analysis of algorithms (at least, the way we understand it here) was born on ...
Updated to follow the recommendations put forth by the ACM/SIGCSE 2001 task force, Analysis of Algorithms raises awareness of the effects that algorithms have on the efficiency of a program and develops the necessary skills to analyze general algorithms used in programs. The text presents the mater...

upper bound on the growth rate of an algorithm’s runtime. It provides a way to classify algorithms based on their worst-case performance. For example, an algorithm with a time complexity of O(n) has a linear growth rate, meaning its runtime increases linearly with the size of the input...
