Hitachi Hokudai Lab. and Hokkaido University Contest 2022 "Future Autonomous Distributed City Development" Awards Ceremony：Details of Winning Algorithms toward Construction of Agricultural Asset-sharing Platform to be Presented at the Lunch Seminar of the

The Hitachi Hokkaido University Laboratory (Hitachi Hokudai Lab.) established on the campus of Hokkaido University is collaborating with Hokkaido University and other stakeholders in the research and development of solutions to societal issues such as the shrinking population, declining birthrate, and aging population in Hokkaido. Also, to realize a sustainable local community, Hitachi Hokudai Lab. is promoting community development that coexists with health, agriculture, food, and energy. This time, Hitachi Hokudai Lab. and Hokkaido University held a marathon-type programming contest (Future Autonomous Distributed City Development). This contest was held on the cloud for one month with the theme of algorithms for optimization problems (spatio-temporal optimization problems) involving multiple complex factors (e.g., working time, movement of farm machinery, and appropriate work timing) that seek practical solutions to improve work planning efficiency for agricultural machinery sharing and other applications. More than 1400 participants registered from all over the world, and more than 190 answer programs were submitted. We will explain the background of this contest, problems, and the commemorative lectures will be given at the Lunch Seminar of 85th National Convention of IPSJ.
