The classic greedy scheduling problem animated: sort by finish time, sweep, and select every compatible activity — with the exchange-argument intuition.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Activity Selection Visualizer is a free, browser-based tool that helps you turn raw numbers into clear charts. The classic greedy scheduling problem animated: sort by finish time, sweep, and select every compatible activity — with the exchange-argument intuition. 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.
Fractional Knapsack Visualizer: Greedy by value density animated: take the densest items whole, split the last one — and see exactly why splitting is what makes greedy optimal here.
Open toolHuffman Coding Visualizer: Huffman coding animated on your own text: merge the two rarest symbols until one tree remains, read off the prefix codes, and see the compression ratio.
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.
Open tool1Activity selection: pick the maximum number of non-overlapping activities. GREEDY KEY: sort by finish time — finishing earliest leaves the most room. Sorted list shown.

Max non-overlapping activities: sort by finish time and sweep. The exchange argument proves greedy optimal here.
