liblbfgs0 - 1.10-8+b1 main

Solves nonlinear optimization problems using the limited-memory BFGS method.
The user specifies a callback C function that returns the value and gradients
of the cost function at a particular operating point. This library estimates
the Hessians from user input, and applies Newton's method iteratively to find a
local minimum of the cost function. This is a small library, written in C with
minimal dependencies.
