I at least plan to keep plugging away providing simple standard- algorithm implementations for stuff on the task list and filling out the docs and unit tests. While things like rootfinding for non-differentiable functions may eventually have a place and may benefit from algorithms that someone can claim copyright ownership of, if no one else does it before I get to it, I will translate my simple newton's method implementation (which is trivial) and submit it. I would appreciate input on what a nice Java interface would look like for rootfinding, initally assuming that the function has a derivative, but ideally extensible to support strategies that do not require differentiability.
