Approximate dynamic programming for real-time control and neural modeling @inproceedings{Werbos1992ApproximateDP, title={Approximate dynamic programming for real-time control and neural modeling}, author={P. Werbos}, year={1992} } Approximate dynamic programming (ADP) is a general methodological framework for multistage stochastic optimization problems in transportation, finance, energy, and other domains. Approximate Dynamic Programming f or Two-Player Zer o-Sum Markov Games. Because the high dimensionality and uncountable state space of our MDP model renders classical dynamic programming solution methods intractable, we instead apply approximate dynamic programming (ADP) solution methods to produce high-quality dispatching policies relative to the currently practiced closest-available dispatching policy.
