How do you determine if an intersecting polygon is self?

To determine if a polygon is self-intersecting using MapObjects, simply intersect the polygon with its own Extent. If the result is Nothing (nil), then the polygon is self-intersecting.

How do you find self-intersection?

A self-intersection will be a singular point of the curve, and the singular points can be found by solving the system of equations [; f(x,y) = f_x(x,y) = f_y(x,y) = 0 ;] , which can again be done with Gröbner bases.
