Gathering of Robots in a Grid with Mobile Faults [PDF]

, 2019
The gathering of two or more agents in a graph is an important problem in the area of distributed computing and has been extensively studied especially for the fault free scenario. In this paper we consider the mobile agents gathering problem in the presence of an adversarial malicious agent which by occupying an empty node might prevent honest agents ...
