## Dynamic system modeling and control

Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later. This simple optimization reduces time complexities from exponential to polynomial. For example, if we write simple recursive solution for Fibonacci Numbers , we get exponential time complexity and if we optimize it by storing solutions of subproblems, time complexity reduces to linear.

Analytic Solutions to the Dynamic Programming Subproblem in Hybrid Vehicle Energy Management Abstract: The computationally demanding dynamic programming DP algorithm is frequently used in academic research to solve the energy management problem of a hybrid electric vehicle HEV. This paper is exclusively focused on how the computational demand of such a computation can be reduced. The main idea is to use a local approximation of the gridded cost-to-go and derive an analytic solution for the optimal torque split decision at each point in the time and state grid.

Dynamic Programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions using a memory-based data structure array, map,etc. 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. So the next time the same subproblem occurs, instead of recomputing its solution, one simply looks up the previously computed solution, thereby saving computation time. This technique of storing solutions to subproblems instead of recomputing them is called memoization. Want to read this story later? Save it in Journal.

Dynamic 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.
