Could you perhaps start a thread about it (for reference), and open
a JIRA report (in project NUMBERS for the meantime, even if it
is probably going to end up in its own new component)?

Several classes in "solvers" can be easily moved to [Numbers] but I'm
not sure all should: It was my intention to create a "rootfinder" module
and move "BrentSolver" which is probably the most generally useful
implementation (in real applications).

Fair enough if the intention were to develop a complete library for
machine learning. ;-)


P.S. Do you know that a potential GSoC candidate is waiting for your feedback?
