Weakly viewing lattice points
Neil R. Nicholson, Roy Sharp · Involve a Journal of Mathematics · 2010
A specific rectangular array of lattice points is investigated.We say that the array is weakly visible from a lattice point not in the array if no point in the array lies on the line connecting the external point to any other point in the array.A lower bound is found for the distance from a weakly viewing point to the array, and a point of minimal distance is determined for arrays of a specific size.A secondary type of visibility is also discussed, and a closest point viewing the array in this style is completely determined.
