Subject [jira] Commented: (MATH-246) Simplex Method Implementation
Date Wed, 25 Mar 2009 19:19:58 GMT

    [ https://issues.apache.org/jira/browse/MATH-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689202#action_12689202

Ben McCann commented on MATH-246:
---------------------------------

LinearEquation -> LinearConstraint is fine by me.  My thought with calling it LinearEquation
was that it could potentially be reused by other algorithms.
GoalType moved from LinearObjectiveFunction to SimplexSolver is okay too.
LinearOptimizer interface is fine (though I'd be curious to see the interface definition and
other implementing classes if you want more feedback)

If you were to remove LinearModel, I assume you would merge it into SimplexSolver?  Then the
constructor would take:
GoalType goal, LinearObjectiveFunction objective, List<LinearConstraint> constraints,
boolean restrictToNonNeagtive, double epsilon
That's fine too or did you have other plans to make adhere to the new interface?

> I've created an implementation of the Simplex algorithm for optimizing systems of constrained
linear equations that I'd like to contribute.
