Researchers have introduced the Quasi-Quadratic Gradient (QQG), a new search direction aimed at speeding up the BFGS method in quasi-Newton optimization. The QQG is calculated by multiplying the inverse Hessian approximation with the current gradient, effectively using local curvature information to refine the search path. This new method has shown theoretical and empirical evidence of faster convergence compared to the standard BFGS approach, while also preserving computational efficiency. AI
