We study the minimum diameter color-spanning set problem which has recently drawn some attention in the database community. We show that the problem can be solved in polynomial time forL1andL∞metrics, while it is NP-hard for all otherLpmetrics even in two dimensions. However, we can efficiently compute a constant factor approximation.
