Quantiles.chooseNextSelection介绍

[英]Chooses the next selection to do from the required selections. It is required that the array allRequired is sorted and that allRequired[i] are in the range [ from, to] for all i in the range [ requiredFrom, requiredTo]. The value returned by this method is the i in that range such that allRequired[i]is as close as possible to the center of the range [ from, to]. Choosing the value closest to the center of the range first is the most efficient strategy because it minimizes the size of the subranges from which the remaining selections must be done.
[中]从所需选项中选择下一个要执行的选项。对于[requiredFrom，requiredTo]范围内的所有i，需要对数组allRequired进行排序，并且allRequired[i]在[from，to]范围内。此方法返回的值是该范围内的i，因此allRequired[i]尽可能接近范围[from，to]的中心。首先选择最接近范围中心的值是最有效的策略，因为它可以最小化必须从中进行其余选择的子范围的大小。
