Hi,

For the convex set case, it seems to me that since N points on a circle can always be shattered, there's always at least one data set of size k that can be shattered by

. Thus, the break point does not exist for this

. So then you can't really verify that

for this case - or can you say that it's trivially true since break point k doesn't even exist? Is this the correct interpretation of this exercise?
