This paper presents a restarted conjugate gradient iterative algorithm for solving ill-posed problems. The damped Morozov's discrepancy principle is used as a stopping rule. Numerical experiments are ...
Conjugate Gradient Methods with Armijo-type Line Searches
unconstrained optimization
font style='font-size:12px;'>
2007/12/11
Two Armijo-type line searches are proposed in this paper for nonlinear conjugate gradient methods. Under these line searches, global convergence results are established for several famous conjugate gr...
