A new project: Mean-field control of planes in real time 1) black dots (Planes are initially allocated in the space randomly) 2) green dots (Target locations/distribution) 3) red dots (Obstacles) Goal of the planes: move to the green dots from the black dots, avoiding self-colliding and colliding with the red dots.
