Abstract
Hierarchical-multivariate spectral gradient method is proposed for unconstrained optimization problems. It is a compound of multivariate spectral gradient method and two-point stepsize gradient method but more flexible than them. And the related algorithm is applied into nonrigid registration of medical image.
