Classes
class	ModuleBase::Opt_CG
	A class designed to deal with optimization problems with CG method. Three forms of CG methods have been implemented, including standard flow to solve the linear equation Ax = b, Polak-Ribire (PR) form and Hager-Zhang (HZ) form to solve general optimization problems min{f(x)}. We adopt following abbreviation x -> solution d -> direction g -> gradient. More...
