Dear David,

>4. Algorithms.  Dale Tonrud does an excellent talk showing how the several
>refinement algorithms are related (from CG to ML).

sorry for a remark non-correlated to the choice of the symposia titles.

Your phrase is very confusing :
- CG (conjugate gradients) is a MINIMISATION TECHNIQUE and
- ML is a CRITERION to be minimised.
         One cannot go from CG to ML
