Computational Geometry Problem

Hi,
First of all, I apologize if this post is unrelated to the scope of the mailing list (I hope not).
I have to find an algorithm to draw the maximum enclosed circle in a polygon, which is slightly different from the "well-known" geometry problem: "maximum empty circle"; in this case, not only all the vertices need to be outside the circle but also the entire perimeter of the polygon must *not* be inside the circle.
I can get the center of the polygon using Voronoi Diagrams: anybody has any suggestions or recomendations of how to calculate its radius?
Also, I would like to avoid as much as possible iterative processes (as they can be slow when dealing with a high number of polygons, that have complex frontiers)...
It would be really appreciated any ideas on this, or even references to libraries that could help me... Im not finding a lot of stuff about this on the web :-/ Im using C/C++ but all ideas are welcome, really...

Thanks in advance for your time!
                                        cheers,
                                               Jo
