We consider the evacuation problem of two robots which are initially located at the center of a unit disk. Both the robots have to evacuate the disk through the exits situated on the perimeter of the disk at an unknown location. The distance between two exits along the perimeter $d$ is given. We consider two different communication models. First, in the wireless model, the robots can send a message to each other over a long distance. Second, in face-to-face communication model, the robots can exchange information with each other ","authors_text":"Debasish Pattanayak, H.
