We consider the separability of two point sets inside a polygon
by means of chords or geodesic lines. Specifically, given
a set of red points and a set of blue points in the interior of
a polygon, we provide necessary and sufficient conditions for
the existence of a chord and for the existence of a geodesic
path which separate the two sets; when they exist we also
derive efficient algorithms for their obtention. We study as
well the separation of the two sets using a minimum number
of pairwise non-crossing chords.
