In this paper, we study the wireless synchronization problem which requires devices activated at different times on a congested single-hop radio network to synchronize their roun...
Let P be a set of n points in R3 . The 2-center problem for P is to find two congruent balls of the minimum radius whose union covers P. We present two randomized algorithms for ...
