Dozens of people are still missing following a landslide on Indonesia's Java island on Saturday that killed at least 25 people. The search continues for 72 people who are believed to have been buried ...

Abstract: Matrix-based approaches in graph theory provide a robust framework for advancing cryptographic and security applications, leveraging adjacency, incidence, and Laplacian matrices to model ...

Abstract: In this paper, we propose the graph neural network (GNN)-based matrix completion technique to reconstruct the de-sired low-rank matrix by exploiting the underlying graph structure of the ...

Given n = 5 and edges = [[0, 1], [0, 2], [0, 3], [1, 4]], return true. Given n = 5 and edges = [[0, 1], [1, 2], [2, 3], [1, 3], [1, 4]], return false. Hint: Given n ...
