Chunlai LiAlgorithmic problem solving × machine learning

About ​

Hi, my name is Li Chunlai — Chunlai is my first name, Li my last. I spend most of my free time on two things: algorithmic problem solving and learning machine learning from the ground up. This site is where both accumulate.

What's here ​

Every page is a plain markdown file in a single repository — no CMS, no database:

• Problem notes — mostly Luogu problems, each with the statement and C++ solutions validated against the samples before they were saved;
• OI notes — topic write-ups on data structures, number theory, graph theory, and friends;
• Machine learning notes — my study notes, from the math basics up to Transformers and reinforcement learning;
• Essays and miscellany — 杂谈, whatever I feel like writing down.

Two generated pages read the whole tree: the Timeline lists every note by date, and the Graph draws which notes reference each other.
