Improved artificial bee colony optimization algorithm
According to the improved artificial bee colony optimization algorithm, chaotic mapping is adopted for an initialized population, the randomness and complexity of a sequence are improved, it is guaranteed that an initial solution in the population has large diversity, the convergence speed of the algorithm is increased, and the global search ability of the algorithm is improved; by updating a nectar source in a variable-dimension manner and adopting updating strategies of different dimensions in different iteration ranges, the search and development capabilities of the algorithm are balanced by adopting gradient dimension updating, the problem of premature convergence can be effectively solved while the convergence speed is increased, and the convergence efficiency is improved. And meanwhile, variable-range neighborhood search is carried out under the guidance of a global optimal solution, so that the probability of learning from a population to excellent individuals is increased, the algorithm enables bees to search around some food sources with good fitness values all the time, the size of the search radius is changed according to the number of iterations, and better food source search is accelerated.
