Space-ground telemetry,track and command(TT&C)resource integrated scheduling problem is a typical large combinative optimization problem,and its optimization process is very complicated.Single ant colony optimization(ACO)strategy has disadvantages of low efficiency and poor solution performance.For this reason,the genetic-ACO hybrid algorithm,(GA-ACO)which combines the ACO with genetic algorithm(GA)is proposed to solve this problem.The GA is used to accelerate the low optimization efficiency due to the lack...
