ComScience Lab

Visualise sorting, searching, graphs, shortest paths, data structures, queues, stacks, hash tables and maze backtracking step by step.

ComScience Lab is an interactive learning app for students, teachers and beginners who want to understand computer science algorithms visually.

Instead of only reading theory, users can step through each algorithm and watch how data changes over time. The app is designed for learning, revision, classroom demonstration and self-study.

Main Features

Sorting Lab Explore 11 sorting algorithms with animated bricks, step-by-step playback and guide notes: Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort, Heap Sort, TimSort, IntroSort, Counting Sort, Radix Sort and Bucket Sort.

Searching Lab Visualise common search methods on sorted arrays: Linear Search, Binary Search, Jump Search, Exponential Search, Interpolation Search and Ternary Search.

Graph Lab Learn BFS and DFS on a visual graph. Watch the queue or stack, visited nodes, current node, target node and active edge update step by step.

Shortest Path Lab Study Dijkstra and A* on a weighted graph. See open sets, current nodes, edge relaxation, distance updates and the final shortest path.

Data Structures Lab Understand how core data structures work: Hash Table with chaining, Stack with parentheses checking, and Queue with round-robin scheduling.

Backtracking Lab Follow a maze solver as it tries cells, marks a path, backtracks from dead ends and finds a solution.
