Hello,
Could someone please outline (just outline) how the ab initio basis sets
of popular programs like Gaussian are optimized nowadays (best alphas and
contraction coefficients): are these varied for a set of small molecules till
the values which give the lowest energies are found? Or are they optimized for
*atoms* ?
  Thanks
