Okabe, Atsuyuki (1945–)

Atsuyuki Okabe received his PhD from the University of Pennsylvania in 1975 and a doctor of engineering degree from the University of Tokyo in 1977. He was the director of the university's Center for Spatial Information Science (CSIS) from 1998 to 2005. He is currently a professor at the University of Tokyo and a member of the Science Council of Japan.

Okabe was one of the first to apply Voronoi diagrams to the spatial competition problem (Hotelling problem) and showed that the equilibrium states in a two-dimensional (2D) space were drastically different from those in a 1D space. Since then, he has extensively studied Voronoi diagrams, and his outcomes were developed into a book, Encyclopedia of Voronoi Diagrams, which provides a general framework for studying Voronoi ...
