Dynamic programming models and applications pdf
[PDF] Dynamic Programming: Models and Applications | Semantic ScholarDynamic programming is both a mathematical optimization method and a computer programming method. The method was developed by Richard Bellman in the s and has found applications in numerous fields, from aerospace engineering to economics. In both contexts it refers to simplifying a complicated problem by breaking it down into simpler sub-problems in a recursive manner. While some decision problems cannot be taken apart this way, decisions that span several points in time do often break apart recursively. Likewise, in computer science, if a problem can be solved optimally by breaking it into sub-problems and then recursively finding the optimal solutions to the sub-problems, then it is said to have optimal substructure. If sub-problems can be nested recursively inside larger problems, so that dynamic programming methods are applicable, then there is a relation between the value of the larger problem and the values of the sub-problems.

Extended version. This paper deals with an endogenous growth model with vintage capital and, more precisely, with the AK model proposed in . In endogenous growth models the introduction of vintage capital allows to explain some growth facts but strongly increases the mathematical difficulties. So far, in this approach, the model is studied by the Maximum Principle; here we develop the Dynamic Programming approach to the same problem by obtaining sharper results and we provide more insight about the economic implications of the model. Finally the applicability to other models is also discussed. Asea and P. Time-to-build and cycles.

Tongtiegang Zhao, Jianshi Zhao; Improved multiple-objective dynamic programming model for reservoir operation optimization. Journal of Hydroinformatics 1 September ; 16 5 : — Reservoirs are usually designed and operated for multiple purposes, which makes the multiple-objective issue important in reservoir operation. Based on multiple-objective dynamic programming MODP , this study proposes an improved multiple-objective DP IMODP algorithm for reservoir operation optimization, which can be used to solve multiple-objective optimization models regardless whether the curvatures of trade-offs among objectives are concave or not. MODP retains all the Pareto-optimal solutions through backward induction, resulting in the exponential increase of computational burden with the length of study horizon. The hypothetical test includes three cases in which the trade-offs between objectives are concave, convex, and neither concave nor convex.
This technique of saving values that have already been calculated is called memoization ; this is the top-down approach, since we first break the problem into subproblems and then calculate and store values. This algorithm is just a user-friendly way to see what the result looks like. Journal of Hydroinformatics 1 September ; 16 5 : - Different variants exist, see Smith-Waterman algorithm and Needleman-Wunsch algorithm.
