The general algorithm of the discrete maximum principle with information feedback is stated briefly. It is applied to obtain solutions for the optimum stage-weight distribution problems of a multistage rocket vehicle. The first problem treats the structure ratio as a constant in each stage, though it may differ stage by stage. The second problem considers the variations in structural factors with stage weight. The third problem obtains the optimum weight distribution which minimizes hardware weight. Specific examples are solved.
