The Fast Fourier Transform (FFT): Most Ingenious Algorithm Ever?
推荐理由
It derives the FFT algorithm from polynomial multiplication and it’s fantastic . I rewatch it every 6 months or so.

说明
这是2020年由Reducible发布的一部讲解,主题归在Algorithms & data structures。它讲的是fast fourier transform这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Reducible's visual walkthrough of the Fast Fourier Transform, motivated by polynomial multiplication. It shows how the FFT's key ideas can be discovered by asking the right questions.这些读者给出的理由,核心是:HN repeatedly calls it a fantastic explanation that made FFT click, with some rewatching it periodically.讲法不绑某一条新闻,过几年仍然可以当材料看。从2021年到2026年,有7位不同的读者在8个不同月份把它推荐出来,其中明确叫别人去看的有5次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把fast fourier transform变成能跟着复述的例子。
