Abstract

The coral reef algorithm has the disadvantages of being easy to fall into local optimum and low precision. In view of the shortcomings of coral reef algorithmꎬ this paper proposes an improved coral reef algorithm. By referring to particle swarm optimizationꎬ Gaussian mutation and simulated annealing algorithmꎬ this algorithm improves the broadcast spawningꎬ asexual reproduction and setting(replacement)mechanisms of coral reef algorithmꎬ which greatly improves the optimization precision of the algorithm and can jump out of the local optimum. In the simulation experimentꎬ the improved coral reef algorithm is respectively compared with ten algorithms such as basic coral reef algorithm and particle swarm algorithm in high ̄dimensional and low ̄dimensional test functions. The experimental results show that the improved coral reef algorithm has better convergence rate and accuracy than other algorithmsꎬ which can still be maintained in the high ̄dimensional test functions.
