Résumé :
In the first half of the talk, I will give a short description of the Difference of Convex functions programming (DC programming), DC algorithms, and their applications.
The second part of the talk concerns the General Art Gallery (AGP) problem. Suppose that an art gallery is given and it is in the shape of a polygon. The classical Art Gallery Problem seeks for determining the minimum number of guards that are sufficient to oversee the whole polygon. It has been proven that this problem is NP-hard, even for very special cases. In this talk, we will see a novel solution approach based on mathematical programming techniques. The approach is based on a Primal-Dual procedure and a DC algorithm. Some numerical experiments have been carried out on different kinds of polygons and the obtained results will be presented.
