Blogs

I write to understand ideas and make them easier to revisit. These three blogs collect contest solutions, mathematical explanations, and paper reviews.

Problem Solving

Contest solutions and the ideas behind them, from algorithms and data structures to techniques for competitive programming.

Mathematics

Definitions, proofs, and worked examples in linear algebra, abstract algebra, mathematical statistics, and topology.

Computer Science

Paper reviews and explanations of machine learning, reinforcement learning, and quantum computation, with the mathematics behind them.
