Abstract
In this paper, we study a variant of the Ants Nearby Treasure Search problem, where n mobile agents, controlled by finite automata, search collaboratively for a treasure hidden by an adversary. In our version of the model, the agents may fail at any time during the execution. We provide a distributed protocol that enables the agents to detect failures and recover from them, thereby providing robustness to the protocol. More precisely, we provide a protocol that allows the agents to locate the treasure in time \(\mathcal{O}(D + D^2/n + Df)\) where D is the distance to the treasure and \(f \in \mathcal{O}(n)\) is the maximum number of failures.
