• About

  The Computational Geometry Week (CG Week) is the premier international forum for advances in computational geometry and its many applications.

  CG Week combines a number of events, most notably the 41st International Symposium on Computational Geometry (SoCG 2025), the associated Media Exposition (CG:ME), workshops, the Young Researchers Forum (CG:YRF), and the CG Challenge (CG:SHOP).

  The 2025 edition is planned to take place in Kanazawa, Japan, June Mon. 23 - Fri. 27, 2025.
  Note that the regular talks will start on Tuesday, June 24th.

  Computational Origami for Art, Science, and Industry

  Abstract: The principle of folding is deeply embedded in nature, enabling intricate functions—from the folding of DNA and proteins to insect wings, brain wrinkles, and the delicate structures of plant leaves and flowers. At the heart of this phenomenon lies the traditional Japanese art of origami, a source of fascination for scientists and engineers alike.
  In this talk, I will share my journey from crafting with paper to developing theoretical foundations, tackling computational challenges, and collaborating with experts to translate these ideas into practical applications. Additionally, I will highlight our interdisciplinary collaboration framework, bringing together artists, scientists, and students to advance both education and research.

  Bio: Tomohiro Tachi is a Professor of Arts and Sciences at the University of Tokyo. He studied architecture and received his Ph.D. in engineering from the University of Tokyo in 2010. He has been designing origami since 2002 and continues to explore three-dimensional and kinematic forms through computation. He has developed computational origami tools, including “Origamizer” and “Freeform Origami,” which are available on his website. He explores form, function, and fabrication in nature and art. His research interests include origami engineering, structural morphology, and computational fabrication. He is engaged in STEAM education at the University of Tokyo, College of Arts and Sciences.

  Parameterized Computational Geometry: Visibility Problems, Geometric Intersection Graphs and Graph Drawing

  Abstract: We will discuss three topics in Computational Geometry that have received significant attention from the perspective of Parameterized Complexity in the past few years. First, we will consider visibility problems, focusing on Art Gallery and Terrain Guarding. Second, we will consider the design of subexponential parameterized algorithms for problems on geometric intersection graphs, particularly (unit) disk graphs. Lastly, we will discuss parameterized graph drawing problems, emphasizing crossing minimization. For each topic, we will briefly discuss some basics, related works, and technical details of a selected result in that area.

  Bio: Meirav Zehavi is a Professor of Computer Science at Ben-Gurion University. Her research centers on parameterized algorithms and complexity, with connections to computational geometry, computational social choice, bioinformatics, and approximation algorithms. She has received several awards and grants, including an ERC grant, the Toronto Prize, the Krill Prize, and the Alon Fellowship. She is also a co-author of the book Kernelization: Theory of Parameterized Preprocessing. A proud mother to two daughters, Keshet and Tevel, Meirav recently completed the first draft of a children's book designed to introduce young readers to computer science.

CG Week is dedicated to providing an environment that is free from harassment, bullying, discrimination, and retaliation for all participants. Starting in 2025, CG Week will be organized as an event of the CG Society. All members of the Society are bound by its Code of Conduct. Only members of the Society can give a presentation and hence at least one author of each accepted paper must become a member of the Society. Society membership is free.
