This paper is concerned with on-line problems where a mobile robot of size D has to achieve a task in an unknown planar environment whose geometry is acquired by the robot during ...
We present improved competitive on-line algorithms for the page replication problem and concentrate on important network topologies for which algorithms with a constant competitiv...
