Scaling symmetric rank one update for unconstrained optimization

A basic disadvantage to the symmetric rank one (SR1) update is that the SRI update may not preserve positive definiteness when starting with a positive definite approximation. A simple remedy to this problem is to restart the update with the initial approximation mostly the identity matrix whenever...
