liblbfgs/DESCR

+This library is a C port of the implementation of Limited-memory 
+Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) method written by Jorge Nocedal. The 
+original FORTRAN source code is available at: 
+http://www.ece.northwestern.edu/~nocedal/lbfgs.html
+The L-BFGS method solves the unconstrainted minimization problem,
+
+    minimize F(x), x = (x1, x2, ..., xN),
+
+only if the objective function F(x) and its gradient G(x) are computable. The 
+well-known Newton's method requires computation of the inverse of the hessian 
+matrix of the objective function. However, the computational cost for the inverse 
+hessian matrix is expensive especially when the objective function takes a large 
+number of variables. The L-BFGS method iteratively finds a minimizer by 
+approximating the inverse hessian matrix by information from last m iterations. 
+This innovation saves the memory storage and computational time drastically for 
+large-scaled problems.
