DARPA launched the Cyber Grand Challenge, a competition to create automatic defensive systems capable of reasoning about flaws, formulating patches and deploying them on a network in real time.

This DARPA Challenge seeks methods to forecast outbreaks and the potential spread of CHIKV throughout the Americas.

The purpose of the competition is to bring crowdsourcing to the problem of creating armored vehicles, with the hope of reducing the design costs by a factor of five.

The DARPA CLIQR Quest is a prize-based challenge that seeks to advance the understanding of social media and the Internet, and explore the role the Internet and social networking plays in the timely communication, wide area team-building and urgent mobilization required to solve broad scope, time-critical problems.

DARPA's Shredder Challenge called upon computer scientists, puzzle enthusiasts and anyone else who likes solving complex problems to compete for up to $50,000 by piecing together a series of shredded documents.

The 2009 DARPA Network Challenge was a prize competition for exploring the roles the Internet and social networking play in the real-time communications, wide-area collaborations, and practical actions required to solve broad-scope, time-critical problems.
