Academic Science JournalThis paper considers the steepest descent algorithm (SD) and the conjugate gradient algorithm (CG) with a new parameter to minimize nonlinear unconstrained problems. We improve a new parameter for the conjugate gradient algorithm (CG).

A new family of conjugate gradient methods [PDF]
, 2009 In this paper we develop a new class of conjugate gradient methods for unconstrained optimization problems. A new nonmonotone line search technique is proposed to guarantee the global convergence of these conjugate gradient methods under some mild ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

An Accelerated Riemannian Conjugate Gradient Method Based on the Barzilai–Borwein Technique
MathematicsThis paper proposes an accelerated Riemannian conjugate gradient method based on the Barzilai-Borwein (BB) technique, termed ABBSRCG, for unconstrained optimization on Riemannian manifolds. Building upon classical Riemannian conjugate gradient frameworks,

A Deflated Version of the Conjugate Gradient Algorithm [PDF]
SIAM Journal on Scientific Computing, 2000 A deflated version of the conjugate gradient algorithm is presented for solving linear systems. The algorithm is useful when a small number of eigenvalues of the iteration matrix are very close to the origin and in cases when multiple right-hand sides are present.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Estimating the unemployment rate using least square and conjugate gradient methods [PDF]
, 2018 Unemployment rate is one of the major issues among Malaysian citizens. The unemployment rate indicates the percentage of the total workforce who are actively seeking employment and currently unemployed.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Differentiating through conjugate gradient [PDF]
Optimization Methods and Software, 2018 We show that, although the conjugate gradient (CG) algorithm has a singularity at the solution, it is possible to differentiate forward through the algorithm automatically by re-declaring all the v...
