JudgeDuck OS (2018)

Participated in early development, Code
JudgeDuck OS is an operating system that strives to accurately and steadily measure the time and space of program execution in programming contests, based on MIT JOS. At present, the stability of the measurement is at least 5 times of Linux, and can meet the traditional needs of the C/C++ language programming contests. It was used as the backend of Judge Duck Online (now replaced by 64-bit OS).

In courses




I have participated in problem-setting in National Olympiad in Informatics (NOI) official contests, including NOI, NOIP (NOI in Provinces), China Team Training (CTT).

I also prepared contests for Codeforces, Universal Online Judge (UOJ), and BestCoder.
