Maybe with some more practice you would have got there. I find I can do the same thing with beer bottles on a friday night. What a shame! Maybe with some more practice you would have got there.

I think not, unless we assume that the sets S_i are finite. However, we should be able to do this with no loss of generality: since x is a convex combination of points from S_i (for each i), we may assume S_i to consist of only those points which contribute to that combination. Yes? In the proof of the Colorful Carathéodory Theorem, is there necessarily some “z” achieving the minimum distance as stated?
