To promote international scientific cooperation, the Japan Society for the Promotion of Science encourages highly qualified researchers from the world over to come to and conduct joint research activities with colleagues at Japanese universities and research institutes. The aim of the short-term fellowship is to provide opportunities for pre-/post-doctoral researchers from the US, Canada and Europe to conduct, under the guidance of their hosts, cooperative research with leading research groups in universities and other Japanese institutions. This fellowship will support the collaborative work with Prof. Atsuo Suzuki and Prof. Mihiro Sasaki at Nanzan University concerning novel exact algorithms to solve common multi-facility location problems with Manhattan distances, including especially the development of new BTST-style approaches.
