Pretty Algorithms
This project is a collection of optimized computational routines and standardized implementations of fundamental computer science algorithms. It serves as an educational library for studying and applying core algorithmic patterns, including dynamic programming, greedy strategies, and recursive decomposition, within a TypeScript environment.
The library distinguishes itself by providing generalized solvers for complex optimization and analysis tasks. It includes specific implementations for resource allocation, such as rod cutting, interval scheduling, and change-making problems, alongside sequence analysis tools like longest common subsequence and maximum subarray identification. These routines are designed to support both educational exploration and practical application in software development.
Beyond these specialized solvers, the repository covers a broad range of essential data management and processing capabilities. This includes standard procedures for sorting and searching, priority queue management, and data compression through prefix-based encoding schemes. The implementation is supported by comprehensive test suites to ensure reliability across its various algorithmic modules.
