Abstract

The embodiment of the present application discloses a method and system for itinerary planning. The method divides the preset population size into NP schemes into M groups according to the niche strategy, and reorganizes the M groups into a group of orderly mating pool; pair the parent schemes in the mating pool, and perform a crossover operation to generate offspring schemes after pairing; execute the mutation operator on the scheme to be mutated, which is the offspring scheme determined according to the mutation rate; execute on the invalid scheme Repair strategy, the invalid solution is a child solution determined according to the total time constraint; perform a replacement operation to determine the child solution entering the next generation; repeat iterations, and determine the target child solution for each group when the end condition is met. The niche strategy is adopted to ensure the diversity of plans, and at the same time, considering the needs of different users, a variety of itinerary plans that meet the needs are provided.
