The interior point method is automatically used to refine results.  It 
can be run using

	Method->{"RandomSearch", Method->"InteriorPoint"}

which will use the nonlinear interior point from several starting 
points.  You can also use

	Method->{"RandomSearch", Method->"InteriorPoint", "SearchPoints"->1}

which will just use a single starting point (and so will be more likely 
to just find a local optimum.)

I apologize for this information not making it into the documentation.
