## Question:Is it possible to find more than one centre of gravity location (focal point) for a scatterplot?

Maple

This is a problem that intrigues me.

I have been thinking about the distribution of n points, p[1], p[2], ..., p[n] in a scatterplot and I am interested in finding the location of a focal point, A, such that the distance from A to each neighboring point is a minimum. I have worked on a routine and this is given in the attached worksheet. In this example, n=20 and the position of A is determined to be [-3.25, 0.99].

Now - here's my question. Suppose I am interested in n-large and, instead of locating one focal point, A, I wish to obtain several,i.e. A, B, C, etc. such that the distances from each of these to their respective neighboring points is also a minimum.

Does any interested party know if this is possible to do and if so, can anyone suggest an approach or routine? If so, I'd be delighted to understand how to solve for this.
