Abstract : The authors maintain that the present general-purpose computers are inadequate for the solution of modern economic and mathematical problems, due to an apparent lack of coordination between the computing and memory units of the computers. For example, in a 3-address machine each arithmetic operation requires going into memory 4 times. Any type of computation is possible, but often the program is too bulky or inefficient. Because of this, certain types of mathematical methods, such as the Monte Carlo method, are unsatisfactory on these machines. Several ways are suggested for increasing the efficiency. One of these consists of connecting a digital general-purpose machine with a small, specialized fast computer. One arrangement worked out by the Mathematics and Economics Branch of the Mathematics Institute of the Siberian Department of the USSR Academy of Science is shown. A high rate of computation is attained by the effective use of algorithms for the arithmetic operations, the use of fixed point, and a decrease in word length. The memory section of the standard programs includes several programs. Part of this memory also provides for rewriting and serves for introducing the standard programs necessary for the solution of the problems. (Author)
