SIMO Retiree Blog

(Yu Peng here) For this post, I'll go through a common idea in competitive programming - dynamic programming - and some of my thought processes when I apply it to problems.

I was lying comfortably and about to bid a temporary farewell to the waking world, when suddenly, out of nowhere, I was attacked by a sudden thought: For what $r$ could I tile a square with rectangles whose sides had ratio $r$?
