DARPA's done ironing out the details for its next Grand Challenge, which revolves around the development of AI-powered radios that work with each other to avoid wireless congestion. The contest will apparently be divided into three year-long phases, starting in 2017. Teams that make it through the preliminary phase will advance to the next stages, ending with a championship event in 2019. The team that comes out on top will take home a $2 million cash prize and could also get into a funded contract with the agency. Teams that finish second and third will get something out of the deal, as well, in the form of $1 million and $750,000 cash prizes, respectively.
