Unconstrained minimization.

Unconstrained minimization using a Newton or Quasi-Newton optimization method that try to minimize the objective function given an initial guess .

The function and the gradient need to be known and supplied.

The default algorithm is a Quasi-Newton search using BFGS updates of the inverse Hessian matrix.
