Abstract: Firefly algorithm is a bionic optimization algorithm based on biological swarm Intelligence which has the advantages of simple concept,few parameters to adjust and easy to realize.However,it can easily get trapped in the local optima especially for high-dimensional optimization function.In literature [1],an improved algorithm based on opposition and dimension was proposed,which is improved in population initialization and algorithm iteration.In this paper,we proposed a new algorithm based on the dimension-weighted method.The algorithm takes into account the current optimal firefly information and part of firefly information.Through the comparison of the experimental results,the improved algorithm embodies the superiority.
