The concepts of convex and non-convex functions play a key role in the study of
optimization. So, with the help of these ideas, some inequalities can also be established …

In this paper, we introduce (h 1, h 2) (h_1,h_2)-preinvex interval-valued function and
establish the Hermite–Hadamard inequality for preinvex interval-valued functions by using …

In this paper, a generalized interval vector space is investigated and defined as an ordered
relation in the form of a bijective linear transformation of its onto a real vector space. The …

This paper is devoted to constructing Wolfe and Mond–Weir dual models for interval-valued
pseudoconvex optimization problem with equilibrium constraints, as well as providing weak …

In this study, a gH-penalty method is developed to obtain efficient solutions to constrained
optimization problems with interval-valued functions. The algorithmic implementation of the …

In this article, gradient based descent line search scheme is proposed to solve interval
optimization problems under generalized Hukuhara differentiability. The innovation and …

A general optimization problem whose parameters and decision variables are intervals, is
known as an enhanced interval optimization problem. This article has focused on nonlinear …

The principles of convexity and symmetry are inextricably linked. Because of the
considerable association that has emerged between the two in recent years, we may apply …

This paper is devoted to the applications of convexifactors on interval-valued programming
problem. Based on the concept of LU optimal solution, sufficient optimality conditions are …

In this paper, we investigate a bilevel interval valued optimization problem. Reducing the
problem into a one-level nonlinear and nonsmooth program, necessary optimality conditions …
