Computational Geometry:
Solving Hard Optimization Problems

Geometric Optimization Challenges

The CG:SHOP Challenge (Computational Geometry: Solving Hard Optimization Problems) is an annual competition dedicated to tackling specific, difficult geometric optimization problems. Originally established as a workshop at Computational Geometry Week (CG Week) in 2019, the Challenge provides a unique platform where the success of proposed solutions is measured based on computational performance on a set of carefully selected benchmark instances. This focus on empirical evaluation marks a shift from traditional computational geometry research, which often emphasizes theoretical approaches.

Each year, the CG:SHOP Challenge invites participants from diverse fields—including computational geometry and combinatorial optimization—to devise and implement innovative solution methods for a new optimization problem. Past challenges have addressed a range of problems, such as computing minimum and maximum area polygons from vertex sets, coordinated motion planning, and minimum convex partitioning. With each challenge, we aim to foster collaboration, rigorous comparison of methods, and an opportunity for hands-on problem-solving experience for students and researchers alike.

Join us in the upcoming CG:SHOP Challenge to push the boundaries of geometric optimization, share ideas, and contribute to the vibrant community of computational problem-solvers at CG Week!
