All Near Neighbor GraphWithout Searching

Edgar Chávez, Verónica Ludueña, Nora Reyes, Fernando Kasián • Journal of Computer Science and Technology (2018)

Given a collection of n objects equipped with a distance function d(·, ·), the Nearest Neighbor Graph (NNG) consists in finding the nearest neighbor of each object in the collection. Without an index the total cost of NNG is quadratic. Usin...

The application of cosine similarity measures with Laplacian energy to q-rung orthopair fuzzy graphs in decision-making problems

Mohamed Atheeque A., Sharief Basha S., Nune Pratyusha, C. Raghavendra Reddy et al. • AIP Advances (2024)

Q-rung orthopair fuzzy sets (q-ROFS), which are better than the intuitionistic and Pythagorean fuzzy sets, are a significant tool for expressing ambiguous information. Their key feature is that their ability to represent a larger space of u...
