To implement the second criterion, you can use the package "Triangulated 
Surface Mesh Simplification" with the Edge_lenght as cost. For the first 
criterion, I do not think there is something ready for that in CGAL.

Note that, to output the polyhedron to the file "filename", you could have 
used the "log" stream directly:

  log << obj;

instead of manipulating the cout.rdbuf().
