不管数据有多大,程序处理花的时间始终是那么多的,我们就说这个程序很好,具有O(1)的时间复杂度,也称常数级复杂度;数据规模变得有多大,花的时间也跟着变得有多长,这个程序的时间复杂度就是O(n),比如找n个数中的最大值;而像冒泡排序、插入排序等,数据扩大2倍,时间变慢...
1947 年,乔治·丹齐格(George Dantzig)提出了一种非常漂亮的算法叫作“单纯形法”(simplex algorithm),它在随机数据中的表现极为不错,但在最坏情况下却需要耗费指数级的时间。因此,很长一段时间,人们都在怀疑,线性规划是否有多项式级的算法。直到 1979 年,人们才迎来了线性规划的第一个多项式级的算法,它是由前...
不管数据有多大,程序处理花的时间始终是那么多的,我们就说这个程序很好,具有O(1)的时间复杂度,也称常数级复杂度;数据规模变得有多大,花的时间也跟着变得有多长,这个程序的时间复杂度就是O(n),比如找n个数中的最大值;而像冒泡排序、插入排序等,数据扩大2倍,时间变慢4倍的,属于O(n^2)的复杂度。 还有一些穷...

A somewhat different type of algorithm is used for ptychography. In this case we do not take just one intensity measurement, but we displace the probe by some vector R, and for multiple different R′s we obtain the intensity patterns |Ψ(k,R)|2=|F{P(r−R)O(r)}|2. The probe P...
