A new modified particle swarm optimization algorithm for linear equation constrained optimization problem was put forward. And the method using this algorithm to train support vector machine was given. In the new algorithm, the particle studies not only from itself and the best one but also from other particles in the population with certain probability. This strengthened learning behavior can make the particle to search the whole solution space better. In addition, the mutation for the particle is considered in the new algorithm. The mutation operation is executed when the particleswarm becomes stagnated, which is decided by calculating the population diversity with the formula presented in this paper. For the specific constraints of support vector machine, a new method to initialize the particles in the feasible solution space was provided. The experiments on synthetic and sonar dataset classification show that our algorithm is feasible and robust for support vector machine training.

Coalition is an important way of cooperation for multi-Agent system. To maximize the summation of the coalition values, and to search for an optimized coalition structure in a minimal searching range, a coalition structure optimizationalgorithm in multi-Agent systems based on particleswarmalgorithm (PSO) is proposed. A comparison is made between the operation performances of Generic algorithm (GA) and particleswarmoptimization in this matter through simulation experiment. The result of the simulation shows the effectiveness of the PSO algorithm.

Aim at the characteristics of optimal operation of cascade hydropower stations, a mathematical model that solves multi-stage optimization problem based on particle swarm optimization algorithm is established. The operating strategy of reservoir was transformed to the variable sequence of reservoir water level array, which is presented by a number string of particle through certain coding form. When the particle meets certain constraints, the performance is evaluated by the predetermined objective function. According to the application research of PSO algorithms and some improve PSO algorithm to the cascade optimal operation in the Yalong River, and the comparative analysis of the performance with GA and ACO algorithm, the advantage of the former one is well presented.

Computing grids utilize Internet or special networks to access computing resources which are geographically widespread, in order to solve complex problems more effectively. Task scheduling in grid plays an important role in grid system. This paper introduces mutation into particleswarmalgorithm. The method makes the algorithm jump out local optimization and search for the global optimal solution in other areas. To some extent, it overcomes the inherent flaw of PSO that falling into local optimization. Using this method in grid task scheduling can not only generate relevant scheme dynamically, and also make the complete time minimum. The experiment shows that the algorithm achieves a better result in task scheduling.

This paper develops RRF neural network based on particleswarmoptimization (PSO) algorithm. It is composed of a RBF neural network, whose parameters including clustering centers, variances of Radial Basis Function and weights are optimized by PSO algorithm. Therefore it has not only simplified the structure of RBF neural network, but also enhanced training speed and mapping accurate. The performance and effectiveness of the proposed method are evaluated by using function simulation and compared with RBF neural network. The result shows that the optimized RBF neural network has significant advantages inspect of fast convergence speed, good generalization ability and not easy to yield minimal local results.
