A new simple and effective method for solving ill-conditioned linear systems is presented in this paper. This method tried mainly not to decrease the error caused in direct solving, instead, it tries to transfer this error to a medium variable. At the same time, a parameter is introduced. In order to obtain the best parameter, PSO is used. An algorithm based on this method is presented, and examples show that this algorithm could solve extremely ill-conditioned linear systems correctly and stably.

The original K-means algorithm is sensitive to the selection of the initial clustering center and unstable in the network intrusion detection application based on data mining. In this paper, the optimization ability of particle swarm optimization(PSO) was used to solve the problem that K-means algorithm is sensitive to the selection of the initial clustering center. Different global optimal solutions were obtained by PSO algorithm and used as the basis of choosing the initial clustering center of K-means clustering algorithm. Based on this idea, the K-means algorithm was improved and a network intrusion detection model was established. Experimental results show that the improved K-means clustering algorithm based on PSO has better clustering effect than original K-means clustering algorithm, and can detect more intrusion behaviors in network intrusion detection.

The tuning approach consists in finding the most suitable configuration of an algorithm for solving a given problem. Machine learning methods are usually used to automate this process. They may enable to construct robust autonomous artifacts whose behavior becomes increasingly expert. This paper focuses on the restriction of this general problem to the field of air planning and more specifically the crew scheduling problem. Metaheuristics are widely used to solve this problem. Our approach consists of using hidden markov model to find the best configuration of the algorithm based on the estimation of the most likely state. The experiment consists of finding the best parameter values of the particle swarm optimization algorithm for the crew scheduling problem. Our approach has shown that it can be a promising solution for automatic optimization of airline scheduling problems. © 2016

particle swarm optimization (PSO) algorithm is a heuristic global optimization technology based on colony intelligence. For improving the searching ability of this algorithm, a search factor is added into the movement of the particle to develop it, and the developed PSO algorithm is used for optimal design of water-supply pipe network. Reliability constraint, which is based on the principle of average distribution flux, is added into the process of optimal design to avoid producing tree pipe network for the reason of economic flux distribution. The algorithm is applied to a simple test network. Comparison with the results of basic PSO algorithm shows that the developed algorithm has stronger global optimizing ability and better search accuracy for optimal design of water-supply pipe network.

Because the network intrusion behaviors are characterized with uncertainty, complexity and diversity, an intrusion detection method based on neural network and particle swarm optimization algorithm (PSOA) is presented in this paper. The novel structure model has higher accuracy and faster convergence speed. We construct the network structure, and give the algorithm flow. We discussed and analyzed the impact factor of intrusion behaviors. With the ability of strong self-learning and faster convergence, this intrusion detection method can detect various intrusion behaviors rapidly and effectively by learning the typical intrusion characteristic information. Utilizing the character that rough set can keep the discern ability of original dataset after reduction, the reduces of the original dataset are calculated and used to train neural network, which increase the detection accuracy. We apply this technique on KDD99 data set and get satisfactory results. The experimental result shows that this intrusion detection method is feasible and effective.

In order to overcome the shortage of premature convergence caused by local optimization in the process of global optimization, an adaptive weight particle swarm optimization algorithm with constriction factor is proposed combined with an analysis of convergence of particle swarm optimization algorithm. The value of the inertia weight is set according to dynamic information about the changes in the objective function value, as to effectively balance the advantages of global optimization against the shortage of local optimization. Four Benchmark function are used for performance test of five different kinds of optimization algorithm, the final results shows that the proposed method has a good ability to slow down the pace of premature convergence, compared to other improved particle swarm algorithm.

Nowadays wind energy is one of the most important source of renewable energy worldwide. Wind power generation is an important form of wind energy utilization. The energy problem has become increasingly prominent, which requires to speeding up the development of wind energy industry. However, the existing wind speed forecasting using grey model is inaccurate. Direct prediction of original wind speed sequence produces large error because of the randomness of wind power. To solve the above problems, a novel method for short term wind speed forecasting based on grey model is proposed in this paper. In order to reduce the error of short term wind speed forecasting, one of the most successful approaches is particle swarm optimization algorithm, which chooses the parameters of grey model to avoid the man-made blindness and enhances the efficiency and capability of forecasting. In the present paper, the wavelet decomposition and reconstruction are used to separate the high frequency signal and the low frequency signal. To verify its efficiency, this proposed method is applied to a wind farm's wind speed forecasting in China. The result confirms that the performance of the method proposed in this paper is much more favorable in comparison with the original methods studied.
