A gradient method exploiting the two dimensional quadratic termination property
Xinrui Li, Yakui Huang
The quadratic termination property is important to the efficiency of gradient methods. We consider equipping a family of gradient methods, where the stepsize is given by the ratio…

A note on -linear convergence of nonmonotone gradient methods
Xinrui Li, Yakui Huang
Nonmonotone gradient methods generally perform better than their monotone counterparts especially on unconstrained quadratic optimization. However, the known convergence rate of th…
