The department of Mathematics organized the international conference "The 23rd Thailand-Japan Conference on Discrete and Computational Geometry, Graphs, and Games (TJCDCGGG2020+1)" by online system on September 3 - 5, 2021. 

The series of the Japan Conference on Discrete and Computational Geometry, Graphs, and Games (JCDCG3) has been held annually since 1997. In 2012, the series of the conference was held at Srinakarinwirot University in Bangkok as “Thailand-Japan Joint Conference on Computational Geometry and Graphs (TJJCCGG 2012)”. Due to the COVID-19 pandemic situation, the event planned in Chiang Mai in 2020 was postponed.

In this conference, there were the talks from invited speakers and presenters around the world, about 150 participants and 61 oral presentations. The additinal information will be found in http://www.math.science.cmu.ac.th/tjcdcggg.
