2016 Workshop on extremal and random phenomenon in discrete mathematics will take place from May 14 to May 15, 2016 in Tianjin, China. The arrival date is May 13, 2016, and the departure date is May 16, 2016. The main purpose of this academic activity is to bring together both international and domestic people working on extremal and probabilistic combinatorics to exchange new ideas and achievements in this area. We hope this workshop will attract more young researchers in China to join in the study of combinatorics.
