The Global Optimization Conference (GOC) is a biannual conference of the International Society of Global Optimization. The next one will be organized in Vilnius, August 23-27, 2027. GOC 2027 continues the tradition of the World Congress on Global Optimization (WCGO) that previously took place in Changsha, China (2009), Chania, Greece (2011), Huangshan, China (2013), Gainesville, Florida (2015), College Station, Texas (2017), Metz, France (2019), Athens, Greece (2021), Athens, Greece (2023), and GOC 2025 in Shanghai, China (2025). The conference offers a forum for researchers and practitioners in the field of global optimization from all over the world.

A primary goal of the GOC is to bring together scientists, engineers, mathematicians and practitioners from a variety of related disciplines, to exchange ideas and present original research results in the theory and applications of global optimization. One of the highlights of this biannual meeting is the announcement of Constantin Carathéodory Prize of the International Society of Global Optimization awarded in recognition of lifetime contributions to the field of global optimization.
