Improving the performance of Stochastic Dual Dynamic Programming

WebbThe stochastic dual dynamic programming (SDDP) algorithm has become one of the main tools used to address convex multistage stochastic optimal control problems. Recently … WebbI do this by extracting the value functions from the SDDP algorithm and using these as a terminal cost in my MPC. Yeah. If you have the integrality, then you should view SDDP as a heuristic that can incorporate uncertainty. So focus not on whether the SDDP.jl finds an optimal policy, but whether the terminal value function improves your MPC. david hutchinson drew barrymore boyfriend https://salermoinsuranceagency.com
