Abstract : Variational problems involving a retarded argument have direct applications to automatic control systems. If the integrand of an initial-type variational problem is itself a sum of functions, each of which depends on just one retardation of the argument, then the problem may be immediately transformed into one which involves no retardation, and thus the difficulties involved in solving differential-difference analogues of Euler's equation may be avoided. It is demonstrated that although the integrands typical of control problems are not usually of this type, they can sometimes be approximated fairly closely by integrands which are, and thus the method may be of direct practical use.
