Modified PSO Algorithm for Solving the Eigenvalues of Matrix

Presently, most of the PSO algorithms for eigenvalues computation take the characteristic polynomial as its fitness function, while for large matrix; it needs a lot of computation for its determination. In order to improve the efficiency of arithmetic operations, a new definition of fitness function, the fitness function calculation of which is much less than the calculation of the determination, can greatly improve the efficiency of algorithms. Finally, several different types of matrix operator cases further validate the effectiveness of the obtained results.
