An updated twostep method for solving interval linear programming: A case study of the air quality management problem
(20191001)Many realworld problems occur under uncertainty. In this paper, we consider interval linear programming (ILP) which can be used to tackle un certainties. Several methods have been proposed by researchers, such as the best ...

Multicriteria allocation model of additional resources based on DEA: MOILPDEA
(20191001)We exploit the relationship between multiobjective integer linear problem (MOILP) and data envelopment analysis (DEA) to develop an approach to a resource reallocation problem. The general purpose of the mathematical ...

Fuzzy endpoint results for ´ Ciri´cgeneralized quasicontractive fuzzy mappings
(20191001)We introduce Ciri´cgeneralized quasicontractive fuzzy mappings and pro vide the necessary and sufficient conditions of having a unique endpoint for such mappings. Then we introduce βψquasicontractive fuzzy mappings, es ...

Solving linear optimal control problems of the timedelayed systems by Adomian decomposition method
(20191001)We apply the Adomian decomposition method (ADM) to obtain a subop timal control for linear timevarying systems with multiple state and control delays and with quadratic cost functional. In fact, the nonlinear twopoint ...

A new regularization term based on second order total generalized variation for image denoising problems
(20191001)Variational models are one of the most efficient techniques for image denoising problems. A variational method refers to the technique of optimizing a functional in order to restore appropriate solutions from observed data ...

An extension of the quasiNewton method for minimizing locally Lipschitz functions
(20191001)We present a method to minimize locally Lipschitz functions. At first, a local quadratic model is developed to approximate a locally Lipschitz function. This model is constructed by using the ϵsubdifferential. We minimize ...

Capturing outlines of generic shapes with cubic B´ezier curves using the Nelder–Mead simplex method
(20191001)We design a fast technique for fitting cubic B´ezier curves to the boundary of 2D shapes. The technique is implemented by means of the Nelder–Mead simplex procedure to optimize the control points. The natural attributes ...

Chebyshev pseudospectral method for optimal control problem of Burgers’ equation
(20191001)In this study, an indirect method is proposed based on the Chebyshev pseudospectral method for solving optimal control problems governed by Burgers’ equation. Pseudospectral methods are one of the most accurate methods ...

A discrete orthogonal polynomials approach for fractional optimal control problems with time delay
(20191001)An efficient direct and numerical method has been proposed to approximate a solution of timedelay fractional optimal control problems. First, a class of discrete orthogonal polynomials, called Hahn polynomials, has been ...

Approximate solution of a system of singular integral equations of the first kind by using Chebyshev polynomials
(20191001)The aim of the present work is to introduce a method based on the Chebyshev polynomials for numerical solution of a system of Cauchy type singular integral equations of the first kind on a finite segment. Moreover, an ...

Differential transform method for conformable fractional partial differential equations
(20191001)We expand a new generalization of the twodimensional differential trans form method. The new generalization is based on the twodimensional differential transform method, fractional power series expansions, and conformable ...

A new approximate inverse preconditioner based on the Vaidya’s maximum spanning tree for matrix equation AXB = C
(20191001)We propose a new preconditioned global conjugate gradient (PGLCG) method for the solution of matrix equation AXB = C, where A and B are sparse Stieltjes matrices. The preconditioner is based on the support graph ...
