Hello!

From Neil Sloane's sequences A063984 and A070911, I infer that the convex lattice 11-gon of minimum area is not yet known. This is remarkable, since the answer is known for 12-gons, 13-gons and 14-gons! Does anyone know about any recent progress toward a solution? Jamie Simpson proved in 1990 that the minimum area must be 19.5, 20, 20.5, 21 or 21.5.

By a convex lattice n-gon, I mean a polygon whose n vertices are points on the integer lattice Z^2 and whose interior angles are strictly less than pi.
