Swim-up and density gradient methods
are variably used depending on the initial sperm count and motility and both the techniques proved equally effective in percentage recovery of sperm motile sperm count.
General congujate gradient method
for non-smooth function 1.
The reduced minimization problem is solved by the direct least squares method, by the global LSQR, by the preconditioned conjugate gradient method
for the normal equation (GPCG), and by the Hu-Reichel method (HR).
Algorithm 851: CG_Descent, a conjugate gradient method
with guaranteed descent.
Based on the basic principle of the phase gradient method
, we can obtain the target line glint error as:
It is solved through the conjugate gradient method
minimizing the residue norm in (11).
The good point about Conjugate Gradient method
is that it automatically generates direction vectors at the previous step.
Preconditioned biconjugate gradient method
of large-scale complex linear equations, Computer, Engineering and Applications 43(36): 19-20 (in Chinese).
Iterative algorithm of a gradient method
used to determine a saddle point of a functional with constraints
The NLP class of optimization problems can, in principle, be solved using several classical local search algorithms and their extensions such as the reduced gradient method
(RG) by Wolfe (1963), the generalized reduced gradient method
(GRG) by Abadie and Carpentier (1969), augmented Lagrangian (AL) by Powell (1969) and Hestenes (1969), sequential quadratic programming (SQP) by Powell (1978) and the interior point method (IP) by Karmarkar (1984).
A sampling of paper topics: skin segmentation based on double-models, a mixture conjugate gradient method
for unconstrained optimization, property preservation of time Petri net reduction, integrated security framework for secure web services, the design and implementation of an electronic farm system based on Google maps, user downloading behavior in mobile internet using clickstream data, and ZigBee-based vehicle access control system, to name just a few.
By enlarging the set of admissible solutions, relaxation increases the instability of the restoration process and this could explain why the topological gradient method
is so efficient.
