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)”. This year, the conference comes back to Thailand again at Chiang Mai University. We have hosted many international academic events in mathematics, and it is our great pleasure to welcome everyone in this place, where nature nurtures beautiful intelligence.

Scope of Conference includes, but not limited to: Discrete Geometry, Computational Geometry, Graph Theory, Graph Algorithms, Complexity, and Winning Strategies of Games and Puzzles.
