Improved bounds for cops-and-robber pursuit
We prove that n cops can capture (that is, some cop can get less than unit distance from) a robber in a continuous square region with side length less than √ 5n and hence that n/...

Bounds on the Greedy Routing Algorithm for Array Networks
We analyze the performance of greedy routing for array networks by providing bounds on the average delay and the average number of packets in the system for the dynamic routing pr...

Better Bounds for Incremental Medians
In the incremental version of the well-known k-median problem the objective is to compute an incremental sequence of facility sets F1 ⊆ F2 ⊆ .... ⊆ Fn, where each Fk contain...

Small Weak Epsilon-Nets in Three Dimensions
We study the problem of finding small weak -nets in three dimensions and provide new upper and lower bounds on the value of for which a weak -net of a given small constant size e...
