The graph search problem is the problem of searching for a mobile evader in a graph by mobile searchers.The edge search game is an offline and centralized version of this problem, and is modeled by a pebble game.Let es(G) be the minimum number of pebbles sufficient to search a graph G in this model.An online and distributed version of this problem has been investigated, and the problem is formalized by mobile agent model.We propose a new online and distributed setting.This setting does not assume artificial tools such that the port number, homebase or whiteboard in the graph.We propose an online search algorithm for es(G) searchers, i.e., this is optimal in terms of the number of searchers. |
