ADN.cn Blog

I founded ADN.cn Library (the blog) in 2006, and have maintained it for 5 years. It used to be a famous blog in the circle of OIers, who are interested in Olympiad in Informatics, and algorithm contests. I share my methods, experience and resources through blogging. In 2010, the domain adn.cn was revoked by China government due to the change of policy of .CN domain, as a result, individual registrations would no longer be entertained. I migrated the blog to a new place http://adn.botao.hu/ and kept it there as an archive for me and others.


There will be no update on this blog, but all resources will remain accessible. Here is a collection of top posts. Recommended items are highlighted in bold.
