W orld C ongress on G lobal O ptimization ( WCGO ) is a biennial conference of the International Society of Global Optimization . The 6 th WCGO will be organized in Metz , France on July 8-10 , 2019 , by Computer Science and Applications Department, LGIPM, University of Lorraine. Homepage: [ https://wcgo2019.event.univ-lorraine.fr/ | https://wcgo2019.event.univ-lorraine.fr/ ] We have received numerous submissions for WCGO 2019 . Nevertheless, given many requests from prospective contributors, we have agreed to extend the paper submission deadline by February 17, 2019 . Submission system is still open at [ https://wcgo2019.event.univ-lorraine.fr/user/submissions | here ] . CALL FOR PARTICIPATION WCGO 2019 will bring together most leading specialists in both theoretical and computational aspects as well as applications of Nonconvex Programming and Global Optimization, highlight recent advances, trends, challenges and to discuss how to expand the role of these fields in several potential high-impact application areas. The conference offers an excellent forum for scientists, engineers, mathematicians from a variety of related disciplines, to exchange ideas and present original research results in the theory and applications of global optimization. WCGO 2019 will be composed of several plenary lectures, invited sessions, and contributed sessions.
