4-dimensional trajectories: path planning for unmanned vehicles

The problem is based on real time computation for 4D (3D+time) trajectory planning for unmanned vehicles (UVs). The ability to quickly predict a 4D trajectory/path enables safe, flexible, efficient use of UVs in a collaborative space is a key objective for autonomous mission and task management. 

The problem/topic proposal will consist of 3 challenges: 
1.      A single UV 4D path planning problem.
2.      Multi UV 4D path planning sharing the same space and time.
3.      Assignment of simultaneous tasks for multiple UVs based on the 4D path finding solution.
