To obtain successively improved control-variable functions<sup>k</sup>u(t), we propose to add a random perturbation du(t) to<sup>k</sup>u(t). A fast analog-computer run then solves the dynamical system equations and computes the given criterion function. If the latter has been improved, then<sup>k+1</sup>u(t)=u(t)+du(t) is stored digitally for the next iteration; otherwise 5u( t) is discarded and a new control pertubation is tried.
