Number of point subsets defined by a polygon

45 Views Asked by At

If $S$ is set of $n$ points in the plane, then $S$ has $2^n$ different subsets. We say that a subset $T\subseteq S$ is "defined by a polygon" if there is a polygon which has $T$ in its interior and $S\setminus T$ in its exterior.

For every $n$, define $F(n)$ as the maximum number of subsets defined by a polygon (maximum over all subsets of $n$ points).

What is an asymptotic bound on $F(n)$ when the defining polygon is:

  • A square?
  • A rectangle?
  • A convex polygon with $d$ sides?
  • Any convex polygon?

Is there a general reference for solving such problems?
