Abstract Due to the decreasing attraction in solving high-dimensional optimization problems, the basic firefly algorithm easily falls into local optimum with low accuracy. Aiming at this problem, the dynamic search firefly algorithm based on improved attraction(ADFA) is proposed in this paper. The minimum attraction concept is presented to enhance the individual communication. By adding the optimal value of objective function, the step size can be adjusted adaptively. Finally, ten benchmark functions from CEC2014 are exploited to validate ADFA. The simulation results show that ADFA obtains higher convergence rate and better accuracy.
