Fujitsu and the Institute of Mathematics for Industry at Kyushu University have developed an AI-based matching technology that uses game theory to automatically calculate an optimal matching of children to daycare centers. Using this technology, a complicated daycare admissions screening that had previously required several days by hand took only seconds. The admissions process of matching children to daycare centers seeks to fulfill as many of the applicants’ preferences as possible based on complex requirements, including applicant priority criteria set by each local government and requests for siblings to be admitted to the same daycare center.
