The comparing experiment shows that the performance of ALCM method is higher than the PAM with large data set,and it is not obviously different between two methods about the value of Cost function.

• 通过比较实验表明:1)随着数据个数的增大；PAM所花费的时间将激剧增大；而ALCM花费时间与数据集个数呈近似线性增长的关系；即ALCM是适应大数据集的.；2)PAM算法和ALCM算法随数据个数增大；二者的代价函数并无明显差异
