The application of multimedia technology and the development of computer networks always affect the lifestyle and behavioral habits of modern people, and also affect the education and learning methods of modern people. The genetic algorithm is called the form of calculation of the evolution algorithm, and it has the characteristics of parallelism and overallity and space search. This form is gradually brought into a large -scale cluster system. The article comprehensively considers the time, reliability, algorithm broadband and cost of each individual, and the demand display from 4 different aspects, and designed in the form of an adaptation function of the art teaching multimedia system to ensure the teaching service of teaching services quality. Eventually combined with the design of the courseware system of art teaching, and discussed the design and research and development of multimedia networks in the form of art teaching. R & D forms mainly include: preparation production of online courseware, development of online courseware, the operation and programming of online courseware, and the test and evaluation of online courseware. This design system research shows that the multimedia network system design under the art teaching is very important, which is the basis of the whole network teaching. For the system design and research of the whole art teaching understanding, it is the need to change and innovate technology, and also the only way for art design.
