Dynamic Programming (DP) is a methodological approach in mathematics and computer science for solving optimization problems. It involves breaking down complex issues into simpler subproblems, utilizing principles of optimality, and storing solutions to construct the final answer efficiently. DP is used in various applications, from computing Fibonacci sequences to optimizing machine learning models, and is distinguished from Linear Programming by its recursive nature and use of memoization.

Dynamic Programming is a strategic approach used to solve complex optimization problems by breaking them down into simpler subproblems
Dynamic Programming is based on the principle of optimality, which states that an optimal solution to a problem can be composed of optimal solutions to its subproblems
Dynamic Programming involves identifying overlapping subproblems, solving them once, storing their solutions, and reusing these solutions to efficiently construct the final solution
The methodology of Dynamic Programming consists of four key steps: defining the structure of the optimal solution, formulating a recursive solution, solving subproblems, and using stored solutions to construct the optimal solution
Dynamic Programming is used in various fields, such as computing the Fibonacci sequence, finding shortest paths in networks, and optimizing decision-making in machine learning models
Dynamic Programming utilizes tables to store solutions of subproblems, enabling the rapid reconstruction of the final solution from stored intermediate results
Dynamic Programming is recursive and deals with problems that have overlapping subproblems, while Linear Programming involves optimizing a linear objective function subject to constraints
Dynamic Programming and Linear Programming use distinct techniques and methods, such as memoization and simplex or interior-point methods, respectively
Understanding the differences between Dynamic Programming and Linear Programming is crucial for choosing the right optimization method for a given problem
Dynamic Programming incorporates decision-making strategies like Minimax and Maximin, which aim to optimize outcomes under uncertainty
These strategies are designed to optimize outcomes under adversarial conditions, such as minimizing potential maximum loss or maximizing potential minimum gain
By integrating these strategies into the Dynamic Programming framework, decision-makers can systematically approach complex problems and determine optimal strategies

Key properties of problems suited for DP
Problems with overlapping subproblems and optimal substructure are ideal for Dynamic Programming.
01
DP solution storage mechanism
Dynamic Programming stores solutions of subproblems in a table or array to avoid redundant calculations.
02
DP subproblem solving strategy
In DP, each subproblem is solved once, its solution is saved, and these solutions are combined to solve the overall problem.
