Welcome to the website of the BOS!

The Bilevel Optimization Society since 2025.

The bilevel optimization society (BOS) is a technical section of the Mathematical Optimization Society (MOS). The goal of the BOS is to create and maintain a community of researchers that recognize their work as related to bilevel optimization, while at the same time expanding its basis and promoting its outreach within and outside academia. This is achieved through the organization of:
  • the International Conference on Bilevel Optimization (ICBO) series and,
  • the dissemination and promotion of research and information related to bilevel optimization.

Upcoming Events
