<div>In the history of artificial intelligence, competitions and challenges (CoCha) have played a major role as milestones of development. Think for instance of Chess, Go, and RoboCup. Time and again we have seen that CoCha motivate to share knowledge with
other researchers, to enhance discussion with multidisciplinary fields inside and outside of Artificial Intelligence, to attract researchers to apply and develop benchmark problems to thoroughly test Artificial Intelligence. Given this important role CoCha
in Artificial Intelligence, the organizers of IJCAI-PRICAI 2020 decided to welcome and streamline competitions and challenges in Artificial Intelligence with official CoCha co-chairs. </div>
