An AC-GADA（ant colony-genetic algorithm data association） algorithm was proposed to deal with the data as-sociation problem for multi-target tracking. This algorithm designed difference pheromone for each ant and improved global pheromone increment model. and combined crossover and mutation strategy with fitness of population model in or-der to improve rate of convergence and avoid ... https://danddcollectiblers.shop/product-category/nativity/
