Dynamic programming is an optimization technique used to solve problems with:
-
Overlapping subproblems
-
Independent subproblems
-
Convex objective functions
-
Linear constraints
A
Correct answer
Explanation
Dynamic programming is used to solve problems with overlapping subproblems, meaning that optimal solutions to subproblems can be reused to solve larger problems.
In dynamic programming, the principle of optimality states that:
-
The optimal solution to a problem can be found by breaking it down into smaller subproblems
-
The optimal solution to a subproblem is independent of the solutions to other subproblems
-
The optimal solution to a problem is always unique
-
The optimal solution to a problem can be found by trying all possible combinations of decisions
B
Correct answer
Explanation
The principle of optimality in dynamic programming states that the optimal solution to a subproblem is independent of the solutions to other subproblems.
