The generalized 4-connectivity of folded Petersen cube networks
AIMS Mathematics, 2022 The generalized $ \ell $-connectivity $ \kappa_{\ell}(G) $ of a graph $ G $ is a generalization of classical connectivity $ \kappa(G) $ with $ \kappa_{2}(G) = \kappa(G) $. It serves to measure the capability of connection for any $ \ell $ vertices.

Partial domination of network modelling
AIMS Mathematics, 2023 Partial domination was proposed in 2017 on the basis of domination theory, which has good practical application background in communication network. Let $ G = (V, E) $ be a graph and $ \mathcal{F} $ be a family of graphs, a subset $ S\subseteq V $ is ...

On the sum of powers of the $ A_{\alpha} $-eigenvalues of graphs
Mathematical Modelling and Control, 2022 Let $ A(G) $ and $ D(G) $ be the adjacency matrix and the degree diagonal matrix of a graph $ G $, respectively. For any real number $ \alpha \in[0, 1] $, Nikiforov recently defined the $ A_{\alpha} $-matrix of $ G $ as $ A_{\alpha}(G) = \alpha D(G)+(1 ...

Multi-strategy self-learning particle swarm optimization algorithm based on reinforcement learning
Mathematical Biosciences and Engineering, 2023 The trade-off between exploitation and exploration is a dilemma inherent to particle swarm optimization (PSO) algorithms. Therefore, a growing body of PSO variants is devoted to solving the balance between the two. Among them, the method of self-adaptive
