英文摘要：

When a mountain function according to the density of the data samples is constructed by Gauss function, through cutting the most of the edge of the Gauss function the computational load is reduced mostly. A PSO algorithm is improved so that it is capable of multi-modal function optimization. Based on tahat a quick mountain clustering based on improved PSO （QMCBIPSO）algorithm is presented and its principle and steps are given. The difference of the quick mountain function and general mountain function and the comparison of their computational loads are indicated. The simulation experimental results show that the QMCBIPSO algorithm computes easily and can find all clustering centers of the data sampies. For the same accuracy the computational load of the QMCBIPSO algorithm is 90% less than that of general algorithms. And it also can search efficiently and correctly every clustering center of the samples.
