Abstract : The solution of boundary-value problems of ordinary and partial differential equations, problems of maximizing and minimizing with boundary conditions (optimization of processes in automatic control), etc.) generally require a large number of computing components if the application of an analog computer is expected to achieve prescribed accuracy. In the article, two modes are introduced for combining the advantages of analog and digital computers. The first consists in extending iterative methods of solution to analog computers. By simple adaptation of the control of working conditions of computing elements they are to be used also with standard d-c analog computers. The second mode is based upon the forming of a certain analogy of time sharing on analog computers - a method associated with digital computers. The introduction of the system of time sharing significantly interferes with the analog computer proper and therefore suits specialized analog control computers. Since the iterative method of solution is practical for any analog computer, it is to be utilized for the purpose of common computational technique. Iteration speeds are up to 50 - 1000 iterations per second. (Author)
