25th Korean Workshop on Computational Geometry

POSTECH, South Korea. June 16-20, 2025

The 25th Annual Korean Workshop on Computational Geometry (KWCG 2025) will be held in POSTECH, South Korea in the week June 16 - June 20, 2025. (Wikipedia, postech.ac.kr)

The aim of the workshop is to provide a forum for researchers working in computational geometry to discuss and work together on research problems. Following the tradition of the preceding workshops, we hope to have active discussions and to work together on research problems, in particular in, but not limited to, the area of computational geometry. Therefore we would like you to bring some interesting open problems that can be explained quickly.

SoCG 2025 will be held in the week after KWCG 2025 in Kanazawa, Japan (June 23 - June 27, 2025). You can combine your trip to KWCG 2025 with SoCG 2025. You can check several ways to get to Kanazawa from here.

Open Problems:

As usual the workshop will mostly consist of research work in small, spontaneously formed groups. We will work on open problems presented by the participants within the first two days of the meeting. Therefore, participants are asked to prepare presentations (~10-15 min.) introducing interesting research topics including open problems.

Venue, Accommodation, and Others:

This workshop will be held at PARK TAE-JOON Digital Library, room 501.

Arrival and Departure

We are planning to have dinner aroun 6pm on Sunday (June 15th), and the workshop will end on Friday (June 20th) at noon.

Accommodation

We booked a block of rooms at the hotel on campus and a hotel near campus (left and right markers). We will collect information on the number of occupants and the schedule for the accommodations around March.
