Developed a 0-1 BFS pathfinding algorithm for the Hardvan/Java repository, focusing on efficient shortest path computation in graphs with edge weights of zero or one. The implementation leveraged Java and emphasized algorithm design and data structures, optimizing traversal by prioritizing zero-weight edges to improve runtime on sparse graphs. Comprehensive unit tests were created to validate correctness across a variety of graph structures and edge cases, ensuring robust performance and reliability. The work was delivered as a single, well-documented commit, reflecting a methodical approach to feature development and testing. No bug fixes were recorded during this period, highlighting focused feature delivery.
