摘要: For the convex polygon P having n vertices entirely contained in a K m vertices, an optimal algorithm with running time O(n + m) is presented to compute and name regions boundary of from which it possible illuminate exterior P. It also shown that this illumination region can be used improve worst case O(nm) related two dimensional simplex coverability so too has m), thus within constant factor.
