Duality theorems for convex problems of Lagrange with time-delay
Department of Electrical and Electronic Engineering and Centre for Process System Engineering, Imperial College of Science Technology and Medicine Exhibition Road, London SW7 2BT, England
Convex problems of Lagrange with time-delay in the state are examined. The state x(t) is constrained in a convex set X(t) for each t. Optimal trajectories satisfy certain subdifferential conditions which involve multipliers that solve some dual, convex problem.
