Now, the strategy here is pretty clear. As often is for the continuous problem. What's the strategy? I pour in the gold till I run out of gold.
现在我们的战略已经很明显了,对连续性问题战略是怎么样的?,我先把所有金子,装进去。
with the continuous knapsack problem as we've formulated it, greedy is good.
因为正如我们已经归越过的,对于一般连续性背包问题贪婪算法很实用。
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。
