The notion of t- fuzzy subring and ideal of a ring was introduced and studied by the author in [10]. In this paper, we introduce the notion of t-anti  fuzzy  subring  (normal  subring)  and  ideal  of  a  ring.  The homomorphic  behavior  of  t-anti  fuzzy  subring  (normal  subring)  and ideal  and  their  inverse  images  has  been  obtained.  A  relationship between  t-fuzzy  subring  (ideal)  and  t-anti  fuzzy  subring  (ideal)  has been established.

The aim of this paper is to introduced the notion of t-intuitionistic fuzzy subalgebra and
t-intuitionistic fuzzy normal subalgebra of BG-algebras. We state and prove some theorems in tintuitionistic
fuzzy subalgebra and t-intuitionistic fuzzy normal subalgebra in BG-algebras. The homomorphic
image and inverse image are investigated in both t-intuitionistic fuzzy subalgebra and
normal subalgebras

A support vector machine (SVM) learns the decision surface from two different classes of the input points. In several applications, some of the input points are misclassified and each is not fully allocated to either of these two groups. In this paper a bi-objective quadratic programming model with fuzzy parameters is utilized and different feature quality measures are optimized simultaneously. An α-cut is defined to transform the fuzzy model to a family of classical bi-objective quadratic programming problems. The weighting method is used to optimize each of these problems. For the proposed fuzzy bi-objective quadratic programming model, a major contribution will be added by obtaining different effective support vectors due to changes in weighting values. The experimental results, show the effectiveness of the α-cut with the weighting parameters on reducing the misclassification between two classes of the input points. An interactive procedure will be added to identify the best compromise solution from the generated efficient solutions. The main contribution of this paper includes constructing a utility function for measuring the degree of infection with coronavirus disease (COVID-19).

International Journal an Fuzzy Systems (IJFS) is a forum for presenting new advances and research results in the fields of Fuzzy Logic Systems. Authors are solicited to contribute to the conference by submitting articles that illustrate research results, projects, surveying works and industrial experiences.All submissions must describe original research, not published or currently under review for another conference or journal.

In this paper, we introduce the concept of residual quotient of intuitionistic fuzzy subsets of ring and module and then define the notion of residual quotient intuitionistic fuzzy submodules , residual quotient intuitionistic fuzzy ideals. We study many properties of residual quotient relating to union, intersection, sum of intuitionistic fuzzy submodules (ideals). Using the concept of residual quotient, we investigate some important characterization of intuitionistic fuzzy annihilator of subsets of ring and module. We also study intuitionistic fuzzy prime submodules with the help of intuitionistic fuzzy annihilators. Many related properties are defined and discussed. KEYWORDS Intuitionistic fuzzy (prime) submodule (ideal), residual quotient intuitionistic fuzzy submodules (ideal), intuitionistic fuzzy annihilator, semiprime ring.

The concept of ($\in, \in \vee q$)-interval-valued fuzzy dot d-ideals in d-algebras is introduced. Relationship among interval-valued fuzzy d-ideal, interval-valued fuzzy dot d-ideal, ($\in, \in$)-interval-valued fuzzy d-ideal,($\in, \in$)-interval-valued fuzzy dot d-ideal, and ($\in, \in \vee q$)-interval-valued fuzzy dot d-ideals are discussed. Conditions for an interval-valued fuzzy d-ideal to be an $(\in,\in \vee q)$-interval-valued fuzzy dot d-ideals are given. Some properties of interval-valued fuzzy relations and interval-valued fuzzy ideals under homomorphism are investigated.

A generic growth of the theory of lattice ordered fuzzy soft group(fsg) is furnished in this paper. Certain characterizations of lattice ordered fuzzy soft group, fuzzy soft group ideal(dual) and fuzzy soft group prime ideal(dual) are attained. The relationship between fuzzy soft group ideal and lattice ordered fuzzy soft group congruence relation has been investigated. Moreover, fuzzy soft group ideal has been applied for finding best mobile network coverage in one's long travel.

In this paper, we propose the concept of complex vague soft sets which are vague soft sets defined in a complex setting. Based on this new concept we define some concepts related to this notion as well as some basic operations namely the complement, union, intersection, AND and OR. The basic properties and relevant laws pertaining to this concept such as the De Morgan's laws are also verified. We introduce the axiomatic definition of the distance function between two complex vague soft sets and subsequently define several distance measures between complex vague soft sets. Finally some of the algebraic properties of these distance measures are verified. Keywords: Complex vague soft set, complex fuzzy set, complex intuitionistic fuzzy set, vague soft set, fuzzy set
