What is a Knapsack DP Visualizer?
A knapsack DP visualizer shows how the 0/1 knapsack dynamic programming table is filled. Each cell answers the best value possible using the first i items and a capacity limit.
This tool lets you paste item names, weights, and values, then inspect the DP table and selected items after backtracking.

How to use this knapsack visualizer
- Paste one item per line with name, weight, and value.
- Set the maximum capacity.
- Click Build table.
- Step through DP cells or run to the end.
- Inspect the selected items and total value.
The visualizer uses 0/1 knapsack rules, so each item can be taken at most once.
Knapsack and dynamic programming
Dynamic programming stores answers to overlapping subproblems. In 0/1 knapsack, the table compares skipping an item against taking it when capacity allows.
If you are studying recursion before DP, try the Recursion Tree Visualizer. If you are comparing table-style algorithms with graph algorithms, use the Dijkstra Algorithm Visualizer.
