[jira] [Created] (MATH-926) Refactor the "o.a.c.m.optim" package

Otto Fowler (Jira)
Gilles created MATH-926:

             Summary: Refactor the "o.a.c.m.optim" package
                 Key: MATH-926
                 URL: https://issues.apache.org/jira/browse/MATH-926
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 3.1
            Reporter: Gilles
            Assignee: Gilles
             Fix For: 4.0

The "optim" package should only refer to the strict definition of an optimization problem: minimizing a cost function.

The non-linear least-squares "optimizers" should be considered as "fitting" algorithms and moved to the "o.a.c.m.fitting" package.
In the "AbstractLeastSquaresOptimizer" class, the handling of weights should be dropped because
# it obscures the algorithm's primary purpose, and
# this feature could be implemented independently (by the user, or in a wrapper).
