Tracing backwards gives you the optimal global alignment I mentioned at the beginning of this section.

通过回溯能够得到本节开始时提到的最优全局比对。

youdao

If you award matches one point, penalize Spaces by two points, and penalize mismatches by one point, the following is an optimal global alignment.

如果为每个匹配字符一分，一个空格扣两分，一个不匹配字符扣一分，那么下面的比对就是全局最优比对。

youdao

(the score of the best local alignment is greater than or equal to the score of the best global alignment, because a global alignment is a local alignment.)

(最佳局部比对的得分要大于或等于最佳全局比对的得分，这是因为全局比对也属于局部比对。)
