Optimization of express route planning based on ant colony algorithm

In order to solve the problems of courier delivery efficiency and service quality due to the poor paths chosen by couriers, this paper constructs a path optimization model for courier delivery from the perspective of the shortest delivery path and the lowest delivery cost, and considers the cycling cost and road cost in the model. By using the ant colony algorithm to realize the iterative solution of all possible distribution paths under the premise that each distribution point is known, the optimal path for courier delivery is finally derived, and the courier points and distribution network of a university are selected for algorithm verification, and the reasonableness of the model and the effectiveness of the algorithm can be derived from the final results.
