One example of a problem that can be solved using dynamic programming is the knapsack problem. The knapsack problem is to find the most valuable items that can be packed into a knapsack of a given weight.
The dynamic programming solution to the knapsack problem works by first creating a table of all possible solutions. The table is indexed by the weight of the knapsack and the value of the items that have been packed into the knapsack.
The algorithm then fills in the table by starting with the smallest possible knapsack and the smallest possible value of the items. The algorithm then calculates the best possible solution for each knapsack and value.
The algorithm terminates when it has filled in the entire table. The solution to the knapsack problem can then be found by looking up the value of the knapsack in the table.
Dynamic programming is a powerful algorithmic technique that can be used to solve a variety of problems. It is especially useful for problems that can be broken down into overlapping subproblems.
Here are some other examples of problems that can be solved using dynamic programming:
Dynamic programming is a complex topic, but it is a powerful tool that can be used to solve a variety of problems. It is worth learning about if you are interested in algorithms and problem solving.
