The classic revenue-maximization DP animated: every first-cut choice tried, best[L] built bottom-up, and the optimal cut list reconstructed.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Rod Cutting Visualizer is a free, browser-based tool that helps you turn raw numbers into clear charts. The classic revenue-maximization DP animated: every first-cut choice tried, best[L] built bottom-up, and the optimal cut list reconstructed. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Visualize the dataset after it has been cleaned enough for reliable labels and numeric values.
Review the preview, copy or download the result, and keep everything local in your browser.
0/1 Knapsack Visualizer: The 0/1 knapsack DP table animated cell by cell: skip-or-take decisions with the exact cells each value reads from, ending at the optimal bottom-right answer.
Open toolCoin Change Visualizer: Fewest-coins DP animated — including the classic case where greedy fails (coins 1, 4, 5 for amount 8) and the table finds 4+4 instead.
Open toolAlgorithm Academy: 35+ classic algorithms animated step by step — searching, counting/radix/bucket sort, dynamic programming tables, greedy, backtracking, KMP, graph algorithms, max flow, and convex hull — with auto-play, next/prev stepping, adjustable interval, and pseudocode that highlights the running line.

1Rod cutting: a rod of length 8 sells in pieces — price list shown. best[L] = max over first-cut sizes c of price[c] + best[L−c].
best[0] = 0for L = 1..N:for first cut c = 1..L:best[L] = max(best[L],price[c] + best[L-c])reconstruct cuts from the choices
Choose the first cut, look the rest up: best[L] = max over c of price[c] + best[L−c] — unbounded knapsack in disguise.
