comment Multiplicative version of convex hull
I am interested in the case in which all points are in $\mathbb{R}^2$. Edited the question to make it clear. One interesting feature of this "multiplicative hull" is that, while the convex hull of two points is the straight segment connecting them, the multiplicative hull of two points is not a straight segment. This raises questions such as: how does the multiplicative hull of a segment looks like? etc.

comment Cutting a paper with the smallest number of cuts
Thanks. If I understand correctly the formula in Wikipedia, the upper bound is less than $2\log_2{n}$. So my algorithm is indeed not optimal.

Yes, I mean "two or more".
