ABSTRACT:
We consider the following geometric optimization problem: find a convex polygon of maximum area contained in a given simple polygon P with n vertices. We give a randomized near linear time (1-epsilon)-approximation algorithm for this problem: in sub quadratic time, we find a convex polygon contained in P that, with high probability, has area at least (1-epsilon) times the area of an optimal solution.
