Yixuan Even Xu


Yao Class 02, IIIS, Tsinghua


Well met! I am Yixuan (Even) Xu (徐翊轩), a senior-year undergraduate student majoring in Computer Science and Technology at IIIS, Tsinghua University (a.k.a. Yao Class, directed by Andrew Chi-Chih Yao).

My research interests lie broadly in theoretical computer science and artificial intelligence, with a focus on designing algorithms with both theoretical guarantees and practical impact. I have worked on several topics centered around algorithmic game theory. See my CV and publications for more details about them.

Besides research, I have been actively participating in competitive programming. See my CV for selected awards in OI, ICPC and CCPC. You can also find me in many online competitive programming platforms like Codeforces, Atcoder and Project Euler.
