Abstract:

For the problem that the cuckoo algorithm is easily limited to the local optimum, the ability of the cuckoo algorithm to local optimization and global optimization is balanced by improving the search step value [α] of the cuckoo algorithm and the probability [pα] of the species of an exotic bird in this paper. Combined with particle filtering the improved cuckoo algorithm replaces the resampling process of particle filtering to solve the problem of particle depletion and low estimation accuracy. The experimental results show that the particle diversity of the improved cuckoo optimized particle filter algorithm is improved, which ensures the estimation accuracy.
