Shor's algorithm, for example, is able to find the period of a function of N bits in polynomial time.
例如 Shor 的算法能在多项式时间内找到一个 N 位函数的周期。
Typically up till now, we've looked at things that can be done in sublinear time. Or, at worst, polynomial time. We'll now look at a problem that does not fall into that. And we'll start with what's called the continuous knapsack problem.
至今为止我们已经处理过,亚线性问题,最多也就是多项式问题,我们现在要看的问题则是不能用这些解决的,我们将要开始讲连续背包问题。
