An efficient algorithm for large-scale extended trust-region subproblems with non-intersecting linear constraints
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Article)
In this paper, we study the extended trust-region subproblem in which the trust-region intersects the ball with m linear inequality constraints (m-eTRS). We assume that the linear constraints do not intersect inside the ...
Quadratic problems with two quadratic constraints: Convex quadratic relaxation and strong lagrangian duality
(
EDP Sciences
, 2021 , Article)
In this paper, we study a nonconvex quadratic minimization problem with two quadratic constraints, one of which being convex. We introduce two convex quadratic relaxations (CQRs) and discuss cases, where the problem is ...
The common solutions of the split feasibility problems and fixed point problems
(
Springer International Publishing
, 2015 , Article)
An extraordinary split problem, which can be regarded as a superimposition of the split feasibility problem and the split fixed point problem, is considered. A superimposed algorithm is presented. The analysis technique ...
A new hybrid extragradient iterative method for approximating the common solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem
(
Hindawi
, 2013 , Article)
We suggest and analyze an iterative scheme for finding the approximate element of the common set of solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem in ...
Revisited carmichael's reduced totient function
(
MDPI AG
, 2021 , Article)
The modified Totient function of Carmichael ?(.) is revisited, where important properties have been highlighted. Particularly, an iterative scheme is given for calculating the ?(.) function. A comparison between the Euler ...
Large-scale global optimization based on hybrid swarm intelligence algorithm
(
IOS Press
, 2020 , Article)
There are numerous large-scale global optimization problems encountered in real-world applications including engineering, manufacturing, economics, networking fields. Over the last two decades different varieties of swarm ...
Entropy-Like Minimization Methods Based on Modified Proximal Point Algorithm
(
University of Toronto Press Inc.
, 2014 , Article)
In this paper we introduce an extension of the proximal point algorithm proposed by Guler for solving convex minimization problems. This extension is obtained by substituting the usual quadratic proximal term by a class ...
On strongly generalized convex stochastic processes
(
Taylor and Francis Ltd.
, 2022 , Article)
In this paper, we introduce the notion of strongly generalized convex functions which is called as strongly η-convex stochastic processes. We prove the Hermite-Hadamard, Ostrowski type inequality, and obtain some important ...
A New Version of Black Scholes Equation Presented by Time-Fractional Derivative
(
Springer International Publishing
, 2018 , Article)
In this article, a new time-fractional-order Black–Scholes equation has been derived. In this derivation, the asset price satisfies in a fractional-order stochastic differential equation. Here, the effect of trend memory ...
Regression-type estimators for adaptive two-stage sequential sampling
(
Springer
, 2013 , Article)
Adaptive two-stage sequential sampling (ATSSS) design was developed to observe more rare units and gain higher efficiency, in the sense of having a smaller variance estimator, than conventional sampling designs with equal ...
