1. Comparative study of spectral steplengths and nonmonotone linear searches / Estudo comparativo de passos espectrais e buscas lineares não monótonas
The Spectral Gradient method, introduced by Barzilai and Borwein and analized by Raydan for unconstrained minimization, is a simple method whose performance is comparable to traditional methods, such as conjugate gradients. Since the introduction of method, as well as its extension to minimization of convex sets, there were introduced various combinations of
