Some clever algorithms might find the closest match faster, like quadtrees or binary space partitioning.

一些聪明的算法可能会发现最接近的匹配速度快，像四叉树或二进制空间分割。

Edit 2: I looked at binary space partitioning as an option of achieving this but I have only been able to find one implementation (in GL2PS), which I'm not sure how to use.

编辑2：我看了看二进制空间划分为实现这一目标的一个选项，但我只找到一个实现(在GL2PS)，我不知道如何使用。

For raising the capacity, this method has used the ray acceleration technology, including that the back gathers and the partition algorithm in binary space and decreasing dimensions.

为提高计算效率，本方法采用了射线加速技术，包括背面采集、二元空间分区算法和降维处理。

They may insert themselves into unused space within a binary so as not to change the size or other characteristics of those files (though they would affect a checksum).

Now, an international team of astronomers has trained the Fermi space-based gamma ray telescope on V407 Cygni, a "binary" system comprising a white dwarf star and a red giant companion, 9, 000 light-years away.
