> In order to investigate
>  * implementations failure on some of the test functions,
>  * lack of good performance (in terms of expected number of evaluations of the objective function),
> it is proposed to add a ["callback"|https://en.wikipedia.org/wiki/Observer_pattern] feature to {{SimplexOptimizer}}.
> The purpose is to track/record simplex transformations during the course of the optimization.
