代码说明:

  This submission contains an interface to a LBFGS-code for unconstrained minimization problems of the form min_{x} f(x) + c*| ilde{x}|, where x are the parameters, f is a scalar valued real function, c is a positive scalar (default value=0), |.| denotes the 1-norm, and ilde{x} is some subset of the parameters x.
