23, 1966 NASA-CR-79120 CFSTI $aquot;TjRT~ The logic design of a small high- speed random walk machine to solve Laplacea#39; s equation is described. To convert the logic diagrams to circuit diagrams, a commercial circuit family is chosen to implement the logic. The basis of choice .... The staring point is the discrete method of stochastic approximations for finding the zero of the regression function. The usualanbsp;...
