AbstractThe recent measure function of Byrd and Nocedal  is considered and simple proofs of some its properties are given. It is then shown that the AL-Bayati (1991) formulae satisfy a least change property with respect to this new measure .The new formula has any extended positive definite matrix of Brouden Type-Updates.
