About

CLRS.Helper

This tool helps you study algorithms from the third edition of CLRS. It allows single-step or continuous execution of pseudocode, setting breakpoints, and tracking recursive function calls to understand algorithm design and correctness.

Highlights
  • Pseudocode single-step and continuous execution
  • Breakpoint setting and status observation
  • Tracking recursive function calls
  • Recording pseudocode execution times
  • Covers algorithms from CLRS 3rd edition
  • Visualizes data structure changes

Refer to The third edition of the book, covering content: 2. Getting Started: Insertion sort, Merge sort; 4. Divide-and-Conquer: Maximum-subarray, Matrix Multiplication[normal, recursive, Strassen’s algorithm]; 6. Heapsort: Heapsort[max-heap, min-heap]; 7. Quicksort: Quicksort; 8. Sorting in Linear Time: Counting sort; 12. Binary Search Trees: Binary search tree[Inorder Walk, Search Recursive, Search Iterative, Minimum Iterative, Maximum Iterative, Successor, Predecessor, Insert, Delete]; 13. Red-Black Trees: Red Black Tree[Insert, Delete]; 15. Dynamic Programming: Rod cutting[Recursive, Top_down, Bottom_up, Print],Longest common subsequence; 16. Greedy Algorithms: Acitivity selection[Recursive, Iterative],Huffman codes; 22. Elementary Graph: Breadth-first search, Depth-first search, Topological sort, Strongly connected components; 23. Minimum Spanning Trees: Minimum spanning tree[Kruskal’s algorithm,Prim’s algorithm]; 24. Single-Source Shortest Paths: The Bellman-Ford algorithm,DAG algorithm,Dijkstra’s algorithm; 25. All-pairs Shortest Paths: All-pairs Shortest paths algorithms[Slow,Faster,The Floyd-Warshall algorithm]; 26. Maximum Flow: The Ford-Fulkerson algorithm; Addition: Tower of Hanoi,N Queens Problem,Comparison of sorting algorithms; The primary features: You can run the pseudo-code single step or continuous, observe the change of parameters and data structures,it can help you to understand the design thought of the algorithm; You can set breakpoints in program and ovserve the status of breakpoint, it can help you to understand why this algorithm is corrcet by using loop invariants; With running-time function stacks and the returning positions,you can track the running process of recursive functions easily, and understand the operation mechanism of computer programs; By recording the performed times of the pseudo-codes can help you to understand the running time of algorithms; I wish this app can be helpful to you;

Explore mathematics in a new light with ClearMath – an innovative app designed to enhance your understanding of mathematical concepts. In the Age of AI, learning is different. Getting an answer is easier than ever, but acquiring knowledge is not the same as truly mastering it. While AI can give you a fact, ClearMath helps you build the mental framework to understand its place in the big picture. We help you connect the dots, turning scattered information into deep, lasting wisdom. Key Features: • Concept Relationship Maps: Visualize the connections between mathematical ideas. • Hierarchical tree structure for concept application, clearly depicting inter-concept relationships. • Comprehensive Concept Explanations: Gain a clearer understanding of each concept, beyond formulas. • Guided Learning Paths: Follow structured routes that build your knowledge systematically. • Progress Tracking: Mark concepts as learned and monitor your advancement. • Favorites System: Create a personal collection of key concepts for efficient review. • Practical Questions & Examples: Engage with problems that reinforce conceptual understanding. • Mathematician Profiles: Learn about the thinkers behind mathematical developments, understanding the context of discoveries. • AI explanations: Powered by Gemini, GROK. ClearMath aims to support mathematical learning by focusing on conceptual understanding, an approach emphasized in modern educational research. Our app helps you view mathematics as an interconnected network of ideas rather than isolated techniques. Whether you're a student seeking deeper insight, an educator looking for teaching aids, or a curious learner interested in mathematical foundations, ClearMath offers a visual approach to exploring mathematical concepts. Enhance your mathematical journey from computation to comprehension.
