The most straightforward approaches to checking the degrees of similarity and differentiation
between two sets are to use distance and cosine similarity metrics. The cosine of the angle …

The q‐rung orthopair fuzzy set (q‐ROFS), originally developed by Yager, is more capable
than that of Pythagorean fuzzy set to deal uncertainty in real life. The main goal of this paper …
