This paper presents a particle swarm optimization (PSO) algorithm for multiobjective problems. PSO is modified by using dynamic neighborhood strategy, new memory updating, and one-dimension to deal with multiple objectives. Several benchmark cases were tested showed that could efficiently find Pareto optimal solutions.

This work explores the H∞ synchronization issue for singularly perturbed coupled neural networks (SPCNNs) affected by both nonlinear constraints and gain uncertainties, in which a novel double-layer switching regulation containing Markov chain persistent dwell-time (PDTSR) is used. The first layer of to characterize stochastic properties systems suffering from random component failures sudden environmental disturbances. Meanwhile, PDTSR, as second-layer regulation, used depict variations...

This paper presents a modified dynamic neighborhood particle swarm optimization (DNPSO) algorithm for multiobjective problems. PSO is by using strategy, new memory updating, and one-dimension to deal with multiple objectives. An extended introduced store global Pareto optimal solutions reduce computation time. Several benchmark cases were tested the results show that DNPSO much more efficient than original other techniques.

The cognitive radio is growing an important interest in wireless communication study. A ad hoc network may take a master-slave tree-based structure some special applications. For master node with limited capability, slave nodes usually use the same frequency to access subnet managed by master. Each can acquire many frequencies for local spectrum sensing process. However, there be no common set of available every node. In this case, we should delete and keep other staying as possible. By...

Recommender systems are designed to solve the overload information. Collaborative filtering based on entire user network is by far most widely recommended algorithm, but it produced large amounts of operational data and has difficulty analyze characteristics products deal with sparsity problem.
