Luc Maisonobe commented on MATH-246:
------------------------------------
Apart fro some non-technical changes, here are the changes I would propose to
add to this contribution:
Rename LinearEquation into LinearConstraint. It is only used for that purpose
and could be confused at first sight with LinearObjectiveFunction.
Remove the LinearModel class, or at least change it to package private. This is
an implementation detail. Users should see the simplest possible package and
deal directly with objective function a set of constraints, a goal type and an
optimizer.
Add a LinearOptimizer interface with an optimize method. This would be more
consistent with the new optimization framework. The SimplexSolver would
implement this interface. Setting solvers first and having a separate method to
actually run them has already been asked for by users for root solvers (see
MATH-218), it would be more consistent to follow the same pattern.
Remove GoalType from LinearObjectiveFunction. It seems better to pass it along
with the objective function and the set of constraints when calling the
optimize method.
Does this seems fair ?
