Dynamic Programming is mainly an optimization over plain recursion. What is DP? In many models, including models with Markov-modulated demands, correlated demand and forecast evolution (see, for example, Iida and Zipkin [10], Ozer and Gallego [23], and Zipkin [28]), the optimal policy can be shown to be a state-dependent base-stock policy. /LastChar 196 491.3 383.7 615.2 517.4 762.5 598.1 525.2 494.2 349.5 400.2 673.4 531.3 295.1 0 0 /Subtype/Type1 Tree DP Example Problem: given a tree, color nodes black as many as possible without coloring two adjacent nodes Subproblems: – First, we arbitrarily decide the root node r – B v: the optimal solution for a subtree having v as the root, where we color v black – W v: the optimal solution for a subtree having v as the root, where we don’t color v – Answer is max{B For example, the Lagrangian relaxation method of Hawkins (2003) Dynamic programming refers to a problem-solving approach, in which we precompute and store simpler, similar subproblems, in order to build up the solution to a complex problem.
