An Arithmetical Condition on the Sizes of Conjugacy Classes of a Finite Group

Algebra Colloquium, 2022
An element [Formula: see text] of a finite group [Formula: see text] is said to be primary if the order of [Formula: see text] is a prime power. We define [Formula: see text] as follows: if [Formula: see text] is a prime power for every primary element [Formula: see text] of [Formula: see text], where [Formula: see text] is the conjugacy class of ...

Two efficient spectral hybrid CG methods based on memoryless BFGS direction and Dai–Liao conjugacy condition

Optimization Methods and Software
The spectral conjugate gradient (CG) method is one of the effective methods for solving unconstrained optimization problems. In this work, we introduce a composite hybrid CG parameter which is a convex combination of two new adaptive hybrid CG parameters.

New Conjugate Gradient Algorithms Based on New Conjugacy Condition

International Conference on Communication, Computing & Security, 2016
The nonlinear conjugate gradient (CG) algorithm is one of the most effective line search algorithms for optimization problems due to its simplicity and low memory requirements, particularly for large-scale problems. However, the results of the new conjugacy conditions are very limited. In this paper, we will propose a new conjugacy condition and two CG

AN ADAPTIVE CONJUGACY CONDITION AND RELATED NONLINEAR CONJUGATE GRADIENT METHODS

International Journal of Computational Methods, 2014
In an attempt to find a reasonable solution for an open problem propounded by Andrei in nonlinear conjugate gradient methods, an adaptive conjugacy condition is proposed. The suggested condition is designed based on an implicit switch from a conjugacy condition to the standard secant equation, using an extended conjugacy condition proposed by Dai and ...
