Approximate Dynamic Programming by Practical Examples Now research.utwente.nl Approximate Dynamic Programming ( ADP ) is a modeling framework, based on an MDP model, that o ers several strategies for tackling the curses of dimensionality in large, multi- period, stochastic optimization problems (Powell, 2011). This chapter aims to present and illustrate the basics of these steps by a number of practical and instructive examples. The practical use of dynamic programming algorithms has been limited by their computer storage and computational requirements. The long-haul, high capacity vehicle costs (per subset of destinations visited) are $$C_{\mathcal{D}'} = (250,350,450,900,600,700,1000)$$ for $$\mathcal{D}' = (\{1\},\{2\},\{3\},$$ {1, 2}, {1, 3}, {2, 3}, {1, 2, 3}), respectively. Although ADP is used as an umbrella term for a broad spectrum of methods to approximate the optimal solution of MDPs, the common denominator is typically to combine optimization with simulation, use approximations of the optimal values of the Bellman’s equations, and use approximate policies.

The first location has coordinate (0, 0) and the last location (location 256) has coordinate (1000, 1000). Dynamic programming (DP) is breaking down an optimisation problem into smaller sub-problems, and storing the solution to each sub-problems so that each sub-problem is only solved once. Each of the subproblem solutions is indexed in some way, typically based on the values of its input parameters, so as to facilitate its lookup.
