Improved genetic algorithm-based travel itinerary planning method

InactiveCN107145961AAvoid local optimaStuck in a local optimumForecastingGenetic algorithmsItinerary planningOlder population
The invention discloses an improved genetic algorithm-based travel itinerary planning method. The method comprises the following steps of firstly performing arrangement according to a sequence of visited cities to form codes; secondly initializing a population by adopting a two-way greedy selection policy; calculating a fitness value of each individual in the population; by adopting roulette wheel selection, selecting the individuals with high fitness from the old population to a new population; performing crossover operation according to an adaptive crossover probability Pci, and selecting multiple parents to perform pairing to generate new individuals; performing mutation operation according to an adaptive mutation probability Pmi, and determining mutant individuals; and finally judging whether a predetermined stop condition is met or not, and if yes, stopping heredity and obtaining an optimal solution, otherwise, calculating the fitness value of each individual in the population. According to the method, a travel itinerary route is planned for users by adopting an improved greedy adaptive genetic algorithm based on a travel itinerary planning model; and through the method, the itinerary planning speed is increased and the algorithm is prevented from falling into local optimal solution.

Artificial intelligence-based travel itinerary planning method and device

The present invention provides an artificial intelligence-based travel itinerary planning method and device. The artificial intelligence-based travel itinerary planning method includes the following steps that: recommendation information selected by a user from a plurality of pieces of recommendation information is received and is adopted as target recommendation information; corresponding travelitineraries are generated according to the target recommendation information; when the travel itineraries meet preset conditions, supplementing processing is performed on each travel itinerary according to the plurality of pieces of recommendation information, so that supplemented travel itineraries are obtained and are adopted as intermediate travel itineraries; the target travel information-based loss functions of each of the intermediate travel itineraries are obtained, and loss functions corresponding to each intermediate travel itinerary are obtained; and an intermediate travel itinerarywhich has the smallest corresponding loss function is determined from the intermediate travel itineraries, and is adopted as a target travel itinerary, and the target travel itinerary is adopted as atravel itinerary planning result. With the artificial intelligence-based travel itinerary planning method and device of the invention adopted, the planning effect of travel itineraries can be effectively improved, and the rationality and reference performance of a planning result can be improved, and user experience can be enhanced.

Travel itinerary planning device based on artificial intelligence

PendingCN112224144AMake planning funImprove self-selection effectInstruments for road network navigationVehicle componentsDriver/operatorTouchscreen
The invention discloses a travel itinerary planning device based on artificial intelligence, and the travel itinerary planning device structurally comprises a rolling shaft cross rod, a filtering radar frame disc, an integrated circuit board, a frame housing, a clamping jaw plate, and a touch screen plate. According to the invention, the filtering radar frame disc and the integrated circuit boardcooperate with each other; a filtering armature frame is erected at the positions of a vacuum inner cavity and a sucker rubber frame which are laterally hoisted through an integrated circuit board tocollect area electric signals, the area electric signals are matched with a center pin electric plate base to form pin branching machine frame scanning coverage type regionalization tourist attractionelectric signal feedback, the operation effect is improved, and the shortest-distance navigation route is improved. Labor force of a driver is saved conveniently, planning pleasure and an autonomousselection effect of a travel itinerary are improved, hobbies of travelers are met, self-guided navigation adapts to travel information transmission and diversified central control management of a vehicle-mounted system is realized, stability of signal receiving and transmitting is protected by a magnetic field of the filtering armature frame, and anti-interference performance of equipment is effectively improved.

Travel itinerary planning device based on meteorological monitoring

The invention discloses a travel itinerary planning device based on meteorological monitoring. The travel itinerary planning device comprises a request receiving unit, a data analyzing unit, a meteorological data obtaining unit, an itinerary planning unit and an itinerary library which are sequentially connected, and further comprises a data updating unit which is connected with the itinerary planning unit and the meteorological data obtaining unit. In the scheme, the travel itinerary planning device receives a planning request of a terminal integrated with travel itinerary planning device, and an itinerary is planned according to the carried planning conditions in combination with travel itinerary information matched with the planning conditions and the corresponding meteorological monitoring data. Furthermore, the device regularly obtains the latest meteorological monitoring data corresponding to a corresponding destination in the planning request, and therefore the travel itineraryis updated. By means of the scheme, the imperfection of planning itinerary information is effectively eliminated; meanwhile, itinerary planning is conducted in combination with real-time meteorological monitoring data, it can be effectively avoided that tourists are delayed by meteorological factors, and therefore the effective utilization of the tourists for vacations is promoted, and user experience is improved.

Tourism planning information processing method and system

The invention discloses a tourism planning information processing method and system, and the method comprises the steps: obtaining the first destination information of a first user; obtaining departure place information of the first user; obtaining budget information of the first user; obtaining idle period information of the first user; constructing a travel strategy model; inputting the first destination information, the departure place information, the budget information and the idle period information of the first user into the travel strategy model to obtain a plurality of travel strategy schemes; and the first user selects and obtains a first travel strategy scheme according to the plurality of travel strategy schemes. The technical problems that the travel itinerary planning scheme is low in matching degree with the user and the travel planning information cannot be intelligently processed are solved, and the technical effects of intelligently analyzing the travel planning related information of the user, optimizing the travel itinerary planning scheme and improving the planning rationality of the travel strategy scheme of the user based on the destination, the departure place, the budget and the idle period are achieved.
