Interval DP animated: every split point k tried for every chain window, the cost table fills diagonal by diagonal, and the optimal parenthesization emerges.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Matrix Chain Multiplication Visualizer is a free, browser-based tool that helps you turn raw numbers into clear charts. Interval DP animated: every split point k tried for every chain window, the cost table fills diagonal by diagonal, and the optimal parenthesization emerges. 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 toolLCS Visualizer: Longest Common Subsequence DP table animated: diagonal extensions on matches, max-of-neighbors otherwise, then the traceback that spells out the LCS.
Open toolMatrix Step Calculator: Determinant, inverse, RREF, rank, product, transpose, and eigenvalues with every row operation animated as a step — in exact fractions.

1Matrix Chain Multiplication: matrices A1(23×4) · A2(4×11) · A3(11×17) · A4(17×8). m[i][j] = fewest scalar multiplications to compute Ai…Aj. Diagonal = 0 (single matrix).

Parenthesize a product of matrices to minimize scalar multiplications — interval DP over chain lengths, trying every split point k.
