Summary: This study proposes a novel dynamic community detection algorithm based on particle swarm optimization, targeting the classification of nodes with similar attributes in networks that change over time. By calculating the resistance distance of each node, the core nodes in the network are identified and the constant community is formed by nodes associated with these core nodes. Knowledge gained from the evolution of core nodes in consecutive time steps is utilized to determine the constant community to be retained. Experimental results on various networks indicate the higher accuracy and stability of the proposed algorithm compared to other well-known algorithms.

Summary: This paper proposes a new multi-objective particle swarm optimization algorithm with a dynamic neighborhood balancing mechanism (DNB-MOPSO) to solve the multi-modal multi-objective optimization problems with the same fitness value for Pareto-optimal solutions.

Summary: This paper proposes a particle swarm optimization algorithm called PSO-ELPM, which balances the exploration and exploitation capabilities of PSO through elite learning, enhanced parameter updating, and exponential mutation operator. The algorithm uses the best-performing particles as exemplars to guide the optimization process and computes self-cognition coefficients based on these elites. It also ensures a smooth distribution of weight among the elites using the inverse of the cube root function, and applies an exponential mutation operator to determine the mutation probability per particle. Comparisons with 10 state-of-the-art PSO variants on the CEC 2017 benchmark functions show that the proposed algorithm achieves higher accuracy with acceptable time complexity.

Summary: More and more studies have shown that circRNAs can be used as disease markers due to their stability. Various computational methods, particularly those utilizing artificial intelligence, have been employed to predict circRNA-disease associations. However, these methods often use single, standard objective functions, leading to low prediction accuracy. This paper proposes a multiobjective evolutionary algorithm called ICDMOE to identify circRNA-disease associations, using matrix factorization and modularity of similarity networks to design four objective functions. Experimental results demonstrate that ICDMOE outperforms other prediction methods and can provide good candidates for biomedical experiments, as confirmed by existing studies, miRNA regulations, and expression profiles.
