------------------------------------
This seems fine to me. Do you intend to also add the Viriginia Torczon's
multidirectional method ?

> This issue refers to classes in package {{optimization.direct}}.
> Currently the class {{NelderMead}} inherits from {{DirectSearchOptimizer}}.
> However the method {{doOptimize}} is implemented in
> {{DirectSearchOptimizer}}. This is backwards from the intended design (where
> an "optimizer" is defined as a class that implements a specific algorithm
> within {{doOptimize}}). According to this "terminology",
> {{DirectSearchOptimizer}} is the optimizer whereas {{NelderMead}} could be
> considered as a specific way to construct a simplex. Indeed, that's what
> seems intended since it overrides the abstract method {{iterateSimplex}}.
> I suggest to create 2 classes that will make it clear the separation between
> the "optimizer" and the "simplex manager".
