Webensures that \([\mathbb{B}f](\mathbb{x}_j)\) is symmetric too and is then called a symmetric rank 1 update algorithm or the SR1 update algorithm. Also, it can be seen that the columns of the update matrix \(\mathbb{\Delta}\) are multiples of each other, making it a rank 1 matrix. The rank 1 update algorithm has an issue with the denominator in Eq.
