THE 'ARKUS' ELECTRONIC SELF-ADJUSTING MATHEMATICAL MACHINE,

Abstract

The Institute of Cybernetics of the Academy of Sciences UkrSSR has developed the 'Arkus' hydrid computer. The machine is capable of solving systems of linear or nonlinear differential equations up to the 8th order with linear or nonlinear boundary conditions, with up to 8 nonlinearities in nonlinear differential equations and up to 6 nonlinear boundary conditions. For this purpose the machine has 32 dc amplifiers, 8 nonlinearity elements, and 8 multipliers. The solution is sought in two iteration modes: (1) Initially, when the tentative solution is far from the desired, the method of the steepest descent is used and (2) Later, when the desired solution is more closely approached, the combinational Newton method is applied.
