Background Knowledge

Initiated by the Association for Computing Machinery (ACM) in 1970, ACM-ICPC is an annual international contest designed to showcase the innovative abilities and teamwork of college students. The contestants need to program, as well as analyze and solve problems under pressure.

The contest consists of two major phases: Regional Finals and a World Final. With a duration of about 9 months, the contest attracts the participation of more than 2,000 colleges and universities from over 100 countries and regions representing 6 continents. Nearly 50,000 college students participated in the event this year.

After more than 40 years of development, ACM-ICPC has become the world's most influential computer contest for college students, and is known as the Olympics of the computer software field. Aiming to promote innovation and teamwork, the contest encourages students to give free rein to their creativity when building new software programs, and helps to test their abilities under intense pressure.

A Peking University team first took part in ACM in 2000, and ranked 4th place in the world. In 2014, the team from PKU consisted of Ni Zekun, Du Yufei, Luo Xiangyu, led by team leader Li Wenxin, deputy dean of the PKU School of Electronics Engineering and Computer Science, as well as their coach, Luo Guojie, a specially-appointed researcher of the PKU School of Electronics Engineering and Computer Science. That team earned a gold medal with a ranking of 3rd place in the world, which was the first time PKU won a gold medal in the ACM-ICPC World Final.
