A hyperbolic penalty method to solve structured convex minimization problems
( Institute of Advanced Science Extension (IASE) , 2020 , Article)This paper presents a decomposition algorithm based on the smooth hyperbolic penalty, which leads to a scheme suitable for parallelized computations. The proposed algorithm can be seen as a separable version of the earlier ... -
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 ... -
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 ... -
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 generalized trust-region sub-problem with additional linear inequality constraints-Two convex quadratic relaxations and strong duality
( MDPI AG , 2020 , Article)In this paper, we study the problem of minimizing a general quadratic function subject to a quadratic inequality constraint with a fixed number of additional linear inequality constraints. Under a regularity condition, we ... -
Hybrid differential evolutionary strawberry algorithm for real-parameter optimization problems
( Bellwether Publishing, Ltd. , 2021 , Article)Evolutionary algorithms (EAs) is a family of population-based nature optimization methods. In contrast to classical optimization techniques, EAs provide a set of approximated solutions for different test suites of optimization ... -
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 ... -
Hermite-Hadamard type integral inequalities for multidimensional general h-harmonic preinvex stochastic processes
( Taylor and Francis Ltd. , 2022 , Article)In this paper, we introduce a new concept of preinvex functions which is called general h-harmonic preinvex for real-valued stochastic processes. Further, we define the multidimensional general h-harmonic preinvex stochastic ... -
Calibration of the double Heston model and an analytical formula in pricing American put option
( Elsevier B.V. , 2021 , Article)This paper proposes a novel approach to pricing of American put option under double Heston model. We develop an analytical solution to the double Heston partial differential equation (double Heston PDE) using the equivalent ... -
Hermite-Hadamard-type inequalities for interval-valued preinvex functions via Riemann-Liouville fractional integrals
