One thing that will make plotting possible is a project I'm working
on. Not ready for use, but here's a summary.
The amath4jtcl project provides an extension for the JTcl project
that allows one to use Commons Math Vectors and Matrices within Tcl
Expressions. In combination with my Swank project, which provides a
Tk like GUI interface in Java, you can do scripted plotting via
JFreeChart. Plotting requires no changes to Commons Math or any Java
code to be written.
The project is at:
http://kenai.com/projects/amath4jtcl
JTcl is an implementation of the Tcl Dynamic Language written in Java:
http://kenai.com/projects/jtcl
Swank is at:
http://kenai.com/projects/swank
I'll make an announcement to this list when amath4jtcl is ready for
people to play with.

Did you use the "MATH_2_X" or the "trunk" repository?
I think "MATH_2_X", but will test with trunk. I think the patch should
be against trunk?
modifiable. Should we create an additional interface extending
MultivariateRealOptimizer which covers this aspect?
No.
All the parameters must be passed as arguments to the constructors.
Ok.
None of the CM algorithms do that.
No logging is a CM limitation and sometimes a problem (e.g. for
debugging).
Adding the possibility to inject a logger/plotter (for instance as
optional
constructor
argument) were only the interface is part of CM would not violate the
"no external libraries requirement". But it would not make logging/
plotting
completely
impossible when using CMA-ES.
The CM "RandomGenerator" should be passed as an argument to the
constructor.
Ok
