In this article, our aim is to consider a class of fuzzy mixed variational-like inequalities (FMVLIs) for fuzzy mapping known as
extended perturbed fuzzy mixed variational-like inequalities (EPFMVLIs). As exceptional cases, some new and classically defined
“FMVLIs” are also attained. We have also studied the auxiliary principle technique of auxiliary “EPFMVLI” for “EPFMVLI.” By
using this technique and some new analytic results, some existence results and efficient numerical techniques of “EPFMVLI” are
established. Some advanced and innovative iterative algorithms are also obtained, and the convergence criterion of iterative
sequences generated by algorithms is also proven. In the end, some new and previously known existence results and algorithms are
also studied. Results secured in this paper can be regarded as purification and development of previously familiar results.
1.Introduction
e boundless research work of fuzzy set and systems [1] has
been devoted in advancement of different fields. It con-
tributes to a vast class knowledge and appears in pure
mathematics and applied sciences as well as operation re-
search, computer science, managements sciences, artificial
intelligence, control engineering, and decision sciences [2].
As a part of these knowledge developments, Chang and Zhu
[3] initiated to introduce a new type of variational inequality
for fuzzy mapping, which is known as fuzzy variational
inequality. In fuzzy optimization, Noor [4–6] studied the
characterization of minimum of convex fuzzy mapping
through fuzzy variational inequality and fuzzy mixed vari-
ational inequality and obtained some advanced and effective
iterative algorithms. Moreover, they showed the parallel
correlation by linking fuzzy variational inequalities and
fuzzy Wiener–Hopf equations. Similarly, they established
parallel correspondence between fuzzy variational inequal-
ities and the resolvent equations for fuzzy mappings and
encouraged some important and novel new iterative algo-
rithms and discussed their convergence criteria. ey also
introduced fuzzy mixed variational inequalities, and by
using the classical auxiliary principle technique, some new
existence theorems and iterative algorithms for fuzzy mixed
variational inequalities are attained. It is worthy to mention
here that one of the most considered generalizations of
convex fuzzy mappings is preinvex fuzzy mapping. e idea
of fuzzy preinvex mapping on the invex set was introduced
and studied by Noor [7]. Moreover, any local minimum of a
preinvex fuzzy mapping is a global minimum on invex set,
and necessary and sufficient condition for fuzzy mapping is
to be preinvex if its epigraph is an invex set.
Furthermore, it has been verified that fuzzy optimality
conditions of differentiable fuzzy preinvex mappings can be
distinguished by variational-like inequalities. Motivated and
inspired by the ongoing research work, many authors dis-
cussed fuzzy variational inequalities and its important
generalizations and its applications in different fields [8, 9].
In the subsequent text, we will review the applications and
