Based on the basic principles and characteristics of discrete cosine transform (DCT), we propose a DCT optimization method using genetic algorithm in order to improve the efficiency of image compression. First, we calculate the error between the reconstructed image and its original one. Then, in order to optimize DCT transform matrix coefficients, we use genetic algorithm to find optimal solution...
This paper presents a Web service composition method which supports the associations of services in order to improve the success rate of Web service composition and the quality of the composite service. Firstly, a context-aware web service composition model is built and this paper introduces the concept of service-correlation matrix which means presenting the context of service components in the form...
This paper sets to research pointing at the threat of microwave weapons when the armed police officers and soldiers encounter in dealing with contingencies and maintaining the stability, and also discusses the shielding effectiveness of electromagnetic shielding fabric. With mental shield as the research object, use the genetic algorithm optimization principle and the HOBBIES software to simulate...
Though the use of mixed programming of Visual C++ language and Matlab software, it realizes the optimization of the warning system of BP neural network model that is based on genetic algorithm. This system can not only quickly query into the diseases incidence about rose powdery mildew, downy mildew, gray mold, it also can predict index of the disease inflection rate of greenhouse rose diseases. It...
Through the application of genetic algorithms (genetic algorithm, simplified as GA) and BP(Back Propation) neural network, I built a prediction model of roses diseases, in which I choose six indicators as the input of network, they are the minimum temperature, maximum temperature, average temperature, minimum humidity, maximum humidity, average humidity in the greenhouse, then I choose three diseases...
This article contributes to solve time optimal path planning of robot applied remote real-time snooker match. According to characteristics of this problem, difficulties and key points, a new method is proposed in this paper for near minimum-time path planning of this problem which converts actual model 1 based on the problem into abstract model 2. And then Matlab program is written to calculate solution...
In this work,we set up public transit planning model by analysising of vehicle dispatching and taking both interest of bus company and passenger into consideration. using the improved genetic simulated annealing algorithm(the improved GA-SA) to carry out optimization for public transit dispatching model,and overcomes the problems such as evolution is slow,precocious, local optimal solution and so...
During the process of pluralistic fertilization model construction, the unreasonable ratio of nitrogen, phosphorus and kalium easily results in the deviation of fertilizing model. This paper has proposed an adaptive algorithm of fertilization model fitting based mixed intelligent computing of GP/GA, and solved the issue of structure and parameters optimization of adaptive fertilization model. This...
Based on the individualized requirements of the customers as regards to reasonable diet, diet medication and so on, this article simulates the nutritionist's experience by artificial intelligence, and uses Internet as the technical platform, so as to introduce to customers a scientifically and perfectly structured menu or diet medication plan based on their preference and health status by using actual-time...
