In complex problems it may, however, be very expensive or infeasible to determine the Hessian matrix A.
This motivates quasi-Newton methods which recursively estimate A of A−1
from the measure...
In this paper,the problem of minimizing a convex function subject to linear constraints is considered.An algorithm which is a combination of DFP variable metric method with generalized gradient projec...
