Quasi-Newton Methods for Solving Nonlinear Programming Problems [PDF]

open access: yesComputer Science Journal of Moldova, 1996
In the present paper the problem of constrained equality optimization is reduced to sequential solving a series of problems of quadratic programming. The Hessian of the Lagrangian is approximated by a sequence of symmetric positive definite matrices. The
