Subject [jira] Commented: (MATH-389) New superclass for "AbstractScalarDifferentiableOptimizer"
Date Tue, 20 Jul 2010 17:42:50 GMT

    [ https://issues.apache.org/jira/browse/MATH-389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12890341#action_12890341
] 

Gilles commented on MATH-389:
-----------------------------

In fact, if we combine both ideas (base class and generics), I think that there is no compatibility
risk:

New base generic interface:
{code:title=BaseMultivariateRealOptimizer.java|borderStyle=solid}
interface BaseMultivariateRealOptimizer<T extends MultivariateRealFunction> {
   // ... All common methods

   RealPointValuePair optimize(T func, GoalType goal, double[] start);
}
{code}

And trivially modified (but backward compatible) "MultivariateRealOptimizer" interface:

{code:title=MultivariateRealOptimizer.java|borderStyle=solid}
interface MultivariateRealOptimizer
extends BaseMultivariateRealOptimizer<MultivariateRealFunction> {}
{code}

> In package {{optimization.general}}, I propose to create a new class: "AbstractScalarOptimizer".
 It would contain all code currently in "AbstractScalarDifferentiableOptimizer" that is not
related to derivatives. "AbstractScalarDifferentiableOptimizer" would then extend that class
to add the derivative-related code.
> This new layer in the hierarchy will be the base class for algorithms that do not use
derivatives.
