Given a set P ofn points in the plane, we wish tofind a set Q ⊂ P ofk points for which the convex hullconv(Q has the minimum area. Wesolve this, and the related problem of finding a minimum area convexk-gon, in timeO(n2log n) for fixedk, almost matching known bounds forthe minimum area triangle problem. Our algorithm is based on finding acertain number of nearest verticalneighbors to each line segment determined by two inputpoints. We use a classical result of Ramsey theory to prove that thesenearest neighbors suffice to determine the minimum convexk-gon.
