and to handle functions with or without explicit derivatives

git-svn-id: https://svn.apache.org/repos/asf/commons/proper/math/trunk@754499 13f79535-47bb-0310-9956-ffa450edef68
 2009-03-14 17:35:49 +00:00
Luc Maisonobe 722fc97a7a started refactoring of optimization framework: 
- created subpackages optimization.direct, optimization.general,
   optimization.linear (currently empty) and optimization.univariate
 - removed packages analysis.minimization and estimation
 - renamed all Cost-related interfaces/classes into Objective
   (this allows both minimization and maximization)
 - added a few new general interfaces

This work is not complete yet. The direct and general packages classes
are very close to the former design, they have almost not been changed
structurally.
