There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The coordination scheme proposed in this work will enable large-scale teams of fixed-wing UAVs to maximize their utilities in zero-sum games. Each team consists of homogeneous units, while heterogeneity exists across teams. Many variables can influence the outcome of such a scenario, such as agent motion dynamics, team size, probability of disabling another agent, communication, and sensing. An effective team strategy is comprised of effective maneuvers for one-on-one scenarios, flexible coordination that leverages the team's offensive force in the changing environment, and accurate opponent assessment and prioritization.
To realize effective teaming, this work details team-tactical approaches to swarm-vs.-swarm games and proposes the development of a coordination schema for distributing a team's members such that the team’s utility is maximized throughout the game. Specifically, this thesis will make the following contributions: 1) Coordination analysis: Execute and analyze simulations of swarm-vs-swarm games to compare coordinated and non-coordinated tactics; 2) Tactical analysis: Examine relationships between the variables affecting such games to establish which are most impactful, and in what situations; and 3) Coordinated tactics: Develop a partitioning algorithm that combines search with the learning of policies for sections of the game space that maximizes the utility of the game space.
