什么是滑窗算法？例子？ [英] What is Sliding Window Algorithm? Examples?

问题描述

在解决几何问题，我读到一篇名为方式滑动窗口算法。

While solving a geometry problem, I came across an approach called Sliding Window Algorithm.

难道真的找不到它的任何学习材料/细节。

Couldn't really find any study material/details on it.

什么是对的算法？

推荐答案

一般来说滑动窗口是一个子列表运行在底层集。即，如果你有一个像数组

Generally speaking a sliding window is a sub-list that runs over an underlying collection. I.e., if you have an array like

[a b c d e f g h]

3大小的滑动窗口将运行在它就像

a sliding window of size 3 would run over it like

[a b c]
  [b c d]
    [c d e]
      [d e f]
        [e f g]
          [f g h]

如果你比如说要计算一个平均运行这是有用的，如果你想创建一个集中的所有相邻对等。

This is useful if you for instance want to compute a running average, or if you want to create a set of all adjacent pairs etc.
