So he's packing and unpacking, packing and unpacking, trying all possible combinations of objects that will obey the constraint. And then choosing the winner. Well, this is like an algorithm we've seen before. It's not greedy.
因此它不断装包和清包,尝试了所有满足约束条件的物品组合,最后选择最优者,这很像我们以前看过的一个算法,这不是贪婪算法。
But on the other hand these advances have also come at a cost. And in this story there's also a sense of longing for the freedom of life in the wild--the innocent, simple, uncomplicated life lived day to day without plans, without toil, in harmony with nature Edenic a somewhat Edenic existence.
但是,换个角度来看,人类付出了代价,才得到这些优点,在这部史诗中,同样存在着,对一种纯真,简单,纯粹生活的向往,每天生活中没有计划,辛劳,与自然和平相处,就像以前的。

Even if we are dualists, as we've noticed before even if the soul is something different from the body it could still be the case, logically speaking, that if the body gets destroyed the soul gets destroyed as well.
就像以前一样,即使我们是二元论者,认为灵魂是不同于肉体的,但从逻辑上来说,仍然可能出现,假如肉体死去,灵魂也随之消亡的情况
So it's really neat to think that your counterparts 100 years ago right here at MIT could have been sitting in a class where they had Lewis as their lecturer, and he's putting forth these ideas -- these are actually his lecture notes, even though it wasn't even published yet, and giving this idea of Lewis structure, which is exactly what we keep using today in order to make a lot of these predictions.
因此会有很棒的感觉,当想一想一百年以前像你们一样,在这上学的同学可能正坐在教室里,听路易斯讲课,而他正在提出这些想法-,-而这些正是他的课堂讲义,尽管当时还没有发表,但已经给出了路易斯结构的思想,这正是我们直到今天都一直在用的,用它来做很多预测。
Now. You might look at that and say, well that's just a lot like what we had over here Right? We had some additive constant plus a simpler version of the same problem reduced in size by 1.
现在你可能会看着这个说,这很像我们以前做过的,对不对?我们用一些附加的常量,加上问题的另外一个规模缩小了1的,简化版本来代替这个问题本身。
We can fill right up our table just like we did before, but now we have included our 2 p z orbital here.
我们可以像以前一样填充表格,但现在我们包括了2pz轨道。
With this, if I can assume that accessing the i'th element of a list is constant, then you can't see that the rest of that analysis looks just like the log analysis I did before, and each step, no matter which branch I'm taking, I'm cutting the problem down in half.
读取数组中的第i个元素,是个常量时间的操作的话,我也就能像以前那样得到,这个算法是对数级复杂度的分析,并且每一步不管我选择哪个区间,我都可以把问题的规模缩小一半。
