The featured-article candidate Shapley-Folkman lemma would benefit from a review of its illustrations. The article has 3 supports and no opposes; the supports did not discuss the illustrations. A FA-specialist editor asked for a review of the illustrations.
There are two new images for the page, as well as an animation.

- All I can say about its illustrations is that "I am impressed". Excellent. Fleet Command (talk) 13:06, 8 October 2011 (UTC)
- Thank you, FleetCommand!
- Most of the images come from other articles, but the two best were custom-contributed by User:David Eppstein, whose image galleries awaken the "inner mathematician/artist" in each of us. :D

- Ouch! These pictures' placement really disfigure this section of talk page, at least on my screen. So, I moved them to the bottom. But in the process I noticed a problem: The alt text is very long. Remember: Alt text is a mean of accessibility. It is for those who cannot see the image and must hear it. So, alt text should not be similar to caption; otherwise, the visually-impaired people will just hear the same text twice. It is a torture for those poor folks. Make sure alt text is something like "illustration" or a short summary. Read help documentations for more info. Fleet Command (talk) 11:12, 9 October 2011 (UTC)
The Shapley–Folkman lemma is illustrated by the Minkowski addition of four sets. The point (+) in the convex hull of the Minkowski sum of the four non-convex sets (right) is the sum of four points (+) from the (left-hand) sets—two points in two non-convex sets plus two points in the convex hulls of two sets. The convex hulls are shaded pink. The original sets each have exactly two points (shown as red dots).
