Abstract
Given a positive integer k and a complete graph with non-negative edge weights satisfying
the triangle inequality, the remote-clique problem is to find a subset of k vertices having a
maximum-weight induced subgraph. A greedy algorithm for the problem has been shown to
have an approximation ratio of 4, but this analysis was not shown to be tight. In this paper, we
