The paper analyzes the performance of support vector regression (SVR) with various parameters which also have different influences and the shortcomings. In order to further improve the forecasting accuracy, aiming at the deficiency in the parameters selection of SVR, the selection of parameters is considered as a compound optimization problem in view of the integrative

Ant Colony Optimization algorithm (ACO) is an efficient heuristic algorithm which is widely used in data mining, routing and addressing, robot planning and other realms. However, slow in convergence and low searching performance still restrict the development of ant colony algorithm, make it not suitable for large scale optimization problems. Therefore, how to improve its

The processing ability, storage, communication ability and energy of sensor nodes in Wireless Sensor Network(WSN) are limited. So how to effectively use the limited energy is the focus of WSN research. Take the structure of WSN network into account, the falt routing algorithm and cluster routing algorithm are investigated in this paper.The flat routing algorithm
