Subcritical Solitons I: Saturable Absorber,rations comparable to the number of clusters. Preconditioning in the quadratic case significantly improves the efficiency of a conjugate gradient algorithm. In fact it transforms a conjugate gradient algorithm to a viable optimization technique widely used in several numerical algebra problems especially when problem’s dimension is large.

Memoryless Quasi-Newton Methods,inear Hestenes-Stiefel algorithm provided that the directional minimization is exact. Having that in mind and the fact that Hager and Zhang do not stipulate condition (2.68) in Theorem 2.14 their main convergence result is remarkable.

Phase Domains and Phase Solitons,us chapter a conjugate gradient algorithm is an iterative process which requires at each iteration the current gradient and the previous direction. The simple scheme for calculating the current direction was easy to extend to a nonquadratic problem ..
