3results about How to "Implement search" patented technology

The application relates to the photovoltaic power generation technical field, in particular to a photovoltaic equipment search method, a management module, a photovoltaic system and a storage medium, the method comprises the following steps: sending a first photovoltaic equipment search instruction to each photovoltaic equipment; based on a first receipt signal sent by a photovoltaic equipment which successfully competes for the first photovoltaic equipment search instruction, determining a first photovoltaic equipment in each photovoltaic string and realizing the search of the first photovoltaic equipment in each photovoltaic string, the first photovoltaic equipment is used for determining a second photovoltaic equipment located in the same photovoltaic string; based on the first photovoltaic equipment, sending a second photovoltaic equipment search instruction to each photovoltaic equipment to realize the search of the second photovoltaic equipment in each photovoltaic string; wherein the second photovoltaic equipment located in the same photovoltaic string as the first photovoltaic equipment participates in the competition. The application only searches the second photovoltaic equipment located in the same photovoltaic string, and the search efficiency is improved.

This invention provides a searchable encryption method, apparatus, device, storage medium, and program product. The method includes: responding to a search trapdoor submitted by a data access tenant, determining a keyword in the search trapdoor; determining whether a matching ciphertext exists based on system public parameters, the keyword, and the trapdoor component of the search trapdoor; determining that a matching ciphertext exists, and sending the intermediate ciphertext corresponding to the ciphertext to the data access tenant, so that the data access tenant can access the data corresponding to the ciphertext according to the data access tenant's tenant key; the search trapdoor is obtained based on the keyword of the data to be accessed by the data access tenant, system public parameters, the data access tenant's tenant key, and the data access tenant's attribute vector; the ciphertext is obtained based on the keyword of the data to be shared by the data sharing tenant, the access vector of the access policy, system public parameters, and offline ciphertext.

The application provides a community searching method and device based on maximum clique search on uncertain graph, and relates to the field of data processing.The method comprises the following steps: obtaining an initial graph corresponding to a social network to be processed; determining reference values of each vertex in the initial graph; deleting vertices with reference values not greater than heuristic solution values in the initial graph to obtain a vertex set corresponding to the heuristic solution values, and determining an intermediate subgraph based on the vertex set; performing multiple search operations on each vertex in the intermediate subgraph, determining a target subgraph with the largest number of vertices based on candidate subgraphs obtained through the search operations, and ensuring that there is an edge between any two different vertices in the target subgraph and the product of the existence probabilities of all edges is greater than a preset probability value; and determining a target social user community in the social network to be processed based on the target subgraph.The application can search for a social user community based on uncertain correlation data between social users.
