Abstract
We consider a
facility location problem, where the objective is to
“disperse” a number of facilities, i.e., select
a given number k of locations from a discrete set of n candidates,
such that the average distance between selected locations
is maximized.
In particular, we present algorithmic
results for the case where vertices are
represented by points in d-dimensional space,
and edge weights correspond to rectilinear
distances. Problems of this type have been considered
before, with the best result being an
approximation algorithm with performance ratio 2.
For the case where k is fixed, we establish a
linear-time algorithm that finds an optimal
solution. For the case where k is part of
the input, we present a polynomial-time
approximation scheme.
