L-BFGS?

[3DTOPO]

This project looks really interesting but I need to use a L-BFGS optimizer. Any chance of it being implemented?

I have my own implementation of L-BFGS using the Accelerate framework, but can't figure out why it's not stable. It works for somethings and not others.

I haven't committed to implementing various other optimizers yet, but it's on my radar.
