Network defense strategy selection method and apparatus based on Markov evolutionary game

The invention relates to a network defense strategy selection method and apparatus based on Markov evolutionary game. The method comprises the following steps: constructing a multi-stage Markov attack and defense evolutionary game model according to dynamic attack and defense game in a network attack and defense process, wherein the model contains a plurality of sub game stages; solving and outputting optimal defense strategies of the stages of the attack and defense game by using an optimal defense strategy selection algorithm for the multi-stage Markov attack and defense evolutionary game model. According to the network defense strategy selection method and apparatus provided by the invention, a dynamic evolution process of network attack and defense in view of the multi-stage Markov attack and defense evolutionary game model, the state skip of the evolutionary stages is described as a random process from the angle of attack and defense confrontation, and the multi-stage Markov evolutionary game is constructed on the basis of the Markov process; the total discount gain of the game is used as a target function, a discount factor eta is imported to perform discount processing on the game gains of different stages, a network security analysis method and a defense technology system are researched and searched, and thus the network defense strategy selection method and apparatus have important practical significance.

Numerical simulation determination method of deep high-stress roadway drilling pressure relief parameter

The invention discloses a numerical simulation determination method of a deep high-stress roadway drilling pressure relief parameter. Before simulation is carried out, a test roadway surrounding rock sample is firstly subjected to a loading and unloading test in a laboratory, an attenuation relationship between a rock sample strength parameter and a damage variable is obtained by fitting and is embedded into a FLAC<3D> (Fast Lagrangian Analysis of Continua) built-in strain softening constitutive model, and an actual measurement mine pressure expression law of a test roadway is taken as a known characteristic value to carry out inversion on the numerical calculation model parameter of a rock mass. A deep roadway drilling pressure relief numerical calculation model is established to simulate and analyze the influence law of a pressure relief drilling orientation, pressure relief opportunity and drilling parameters (diameter, length and inter-row spacing) on the stability of roadway surrounding rock, and a determination method of each factor which affects a pressure relief effect is put forward, and a drilling pressure relief technology system is perfected. The numerical simulation determination method considers the mutual action relationship of a pressure relief degree and the stability of the surrounding rock while pressure relief drilling parameters are determined, and the designed pressure relief drilling can perform a maximum pressure relief effect on a premise that the stability of the surrounding rock is guaranteed. The method is simple and exhibits high application value.

Technology System to Develop and Support Community News Services with Multi-Dimensional Marketing and Distributed Computing.

A system to create independent, local, online news services is described. User created content is aggregated to create local news services based on geographical segments and independent content contributors. Content is gathered from independent members and then segmented into web pages. Web pages utilize databases to segment the news content based on population by physical location. The content is then further segmented into categories and areas of interest. Individuals, who want to contribute content, are required to become members of a multi-level marketing network. The multi-level marketing network of members monitors an individual member's content that they provide to the news service. A rating system enables members and consumers to evaluate the content. Members are compensated on revenue that they and the members in their multi-level marketing group produce by marketing advertising and business services. The News Event and News Alert System Architecture depicts the major components of the news event and alerting system. The NDS is the primary network service used by MANA. News events are collected and analyzed. Location and category features are compared to each MANA location and category preferences and alerts are generated.

Intelligent early warning method for surrounding vehicle with abnormal driving state

InactiveCN105303890ALow costSuitable for unified mandatory promotion and popularizationAnti-collision systemsData synchronizationState parameter
The invention discloses an intelligent early warning method for a surrounding vehicle with an abnormal driving state. Vehicle driving state parameters are read via a roadside relay end or a vehicle-mounted reading end, the data are simultaneously submitted to a backstage system or a vehicle-mounted processing system, the backstage system or the vehicle-mounted processing system tracks or marks a vehicle driving electronic trajectory, vehicle instant state parameters comprise a driving speed, a driving direction and an inter-road position instant state, whether the vehicle driving state is abnormal is judged, or after the abnormal type is further confirmed, vehicle abnormal state warning information is sent to the vehicle. As the widely-used RFID technology is adopted, the cost is lower, the application is more convenient, and the method can be forced to be promoted by the government in a unified mode; according to the technology system for intelligent warning, judging and recognizing the abnormal driving vehicle, the surrounding other driving vehicles are warned instantly, effective and reasonable avoidance measures are adopted, and traffic safety accidents can be prevented from happening; and a special global meaning is provided for ensuring safe vehicle driving.
