There are n points in the plane and each point is painted by one of m colors where m ≤ n. We want to select m different color points such that (1) the total edge length of resulting minimal spanning tree is as small as possible; or
(2) the total edge length of resulting minimal spanning tree is as large as possible; or (3) the perimeter of the convex hull
of m different color points is as small as possible. We prove NP-completeness for those three problems and give approximations
algorithms for the third problem.
