Horton, J., D.2023-03-012023-03-011982https://unbscholar.lib.unb.ca/handle/1882/14921Erdos has defined g(n) as the smallest integer such that any set of g(n) points in the plane, no three collinear, contains the vertex set of a convex n-gon whose interior contains no point of this set. Arbitrarily large sets containing no empty convex 7-gon are constructed, showing that g(n) does not exist for n > 7. Whether g(6) exists is unknown.http://purl.org/coar/access_right/c_abf2technical reportComputer Science
