Asynchronous Deterministic Rendezvous in Graphs
Two mobile agents (robots) having distinct labels and located in nodes of an unknown anonymous connected graph, have to meet. We consider the asynchronous version of this well-studied rendezvous problem and we seek fast deterministic algorithms for it. Since in the asynchronous setting meeting at a node, which is normally required in rendezvous, is in general impossible, we relax the demand by ...
متن کاملAsynchronous Deterministic Rendezvous in Bounded Terrains
Two mobile agents (robots) have to meet in an a priori unknown bounded terrain modeled as a polygon, possibly with polygonal obstacles. Robots are modeled as points, and each of them is equipped with a compass. Compasses of robots may be incoherent. Robots construct their routes, but the actual walk of each robot is decided by the adversary that may, e.g., speed up or slow down the robot. We co...
متن کاملAsynchronous Deterministic Rendezvous on the Line
We study the rendezvous problem in the asynchronous setting in the graph of infinite line following the model introduced in [13]. We formulate general lemmas about deterministic rendezvous algorithms in this setting which characterize the algorithms in which the agents have the shortest routes. We also improve rendezvous algorithms in the infinite line which formulated in [13]. Two agents have ...
متن کاملPolynomial Deterministic Rendezvous in Arbitrary Graphs
The rendezvous problem in graphs has been extensively studied in the literature, mainly using a randomized approach. Two mobile agents have to meet at some node of a connected graph. We study deterministic algorithms for this problem, assuming that agents have distinct identifiers and are located in nodes of an unknown anonymous connected graph. Startup times of the agents are arbitrarily decid...
متن کاملAsymptotically Optimal Deterministic Rendezvous
In this paper, we address the deterministic rendezvous in graphs where k mobile agents, disseminated at different times and different nodes, have to meet in finite time at the same node. The mobile agents are autonomous, oblivious, labeled, and move asynchronously. Moreover, we consider an undirected anonymous connected graph. For this problem, we exhibit some asymptotical time and space lower ...
