class ROOT::Math::GSLSimAnMinimizer: public ROOT::Math::BasicMinimizer


   GSLSimAnMinimizer class for minimization using simulated annealing
   using the algorithm from
   <A HREF="http://www.gnu.org/software/gsl/manual/html_node/Simulated-Annealing.html">
   GSL</A>.
   It implements the ROOT::Minimizer interface and
   a plug-in (name "GSLSimAn") exists to instantiate this class via the plug-in manager
