A swarm intelligence optimization for particle filter

To the problem of particle degeneracy and needing a large sample size for particle diversification, the swarm intelligence methodology was introduced into particle filter. Artificial fish swarm algorithm was given to solve particle destitution by means of optimization of particle filtering. First, the principium of particle filtering and some problems about it were pointed out. Then blending artificial fish swarm algorithm into particle filtering makes particle swarm move to the region of high likelihood. As a result, the problem of particle destitution is solved. Examples testify the viability of the proposed approach.
