Three-way decisions provide a trisecting-and-acting framework for complex problem solving.
For a cost-sensitive decision-making problem under multiple levels of granularity, sequential …

Covering based multigranulation rough fuzzy set, as a generalization of granular computing
and covering based rough fuzzy set theory, is a vital tool for dealing with the vagueness and …

The concept of patterns is the basis of sequence analysis. There are various pattern
definitions for biological data, texts, and time series. Inspired by the methodology of three …

To improve the utilization of rough sets, some novel uncertain models via rough sets have
been appeared. Although many rough set models can only handle some intuitionistic fuzzy …

By combining covering based rough sets, fuzzy rough sets, and multigranulation rough sets,
we introduce covering based multigranulation fuzzy rough set models by means of fuzzy β β …

Covering based intuitionistic fuzzy (IF) rough set is a generalization of granular computing
and covering based rough sets. By combining covering based rough sets, IF sets and fuzzy …

Fuzzy set theory was introduced by Lotfi Zadeh in 1965, as a generalization of classical set
theory, for representing imprecise and vague phenomena. The concept of fuzzy graphs was …

The notion of covering based multigranulation fuzzy rough set (CMGFRS) models is a
generalization of both granular computing and covering based fuzzy rough sets. Therefore it …

Covering-based rough set is an important extended type of classical rough set model. In this
model, concepts are approximated through substitution of a partition in classical rough set …

This paper considers a class of bi-matrix games involving two players with their payoffs
matrices having entries from the set of trapezoidal intuitionistic fuzzy numbers. We …
