Abstract: Proposed a new quantum multi-objective ant colony algorithm.In the ant colony algorithm based on the introduction of quantum theory,quantum computation and ant colony fusion,and for solving multi-objective problem.The core of the algorithm is introduced in the colony quantum quantum algorithm and quantum state vector,respectively,and the revolving door to update the pheromone.The ability of global optimization algorithm and population diversity than improved ant colony algorithm,the algorithm was tested,the results shows that the algorithm for solving Multi-objective problem is an effective algorithm.
