Using DEPSO could avoid falling into the partial optimal solution which is common to single optimization algorithm. After the algorithm import the chiasma or variation operations, the adaptability of the algorithm has made a lot of improvement. The result of experiment which chose the Double Cavity Jaw Crusher for object of simulation shows that, using DEPSO algorithm to find the best atom of signal decomposition based on MP of signal feature extraction, the searching speed, efficiency and accuracy of decomposition has been improved
greatly.
