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).
