During June 2025, Andante Soft refactored the shuffling and random number generation logic in the Cysharp/ZLinq repository, focusing on improving both performance and reliability. Leveraging C# and advanced algorithm implementation skills, Andante replaced the existing shuffle methods with Xoshiro256** to deliver faster and more reliable Shuffle() and PartialShuffle() operations. The work also addressed a bias issue in the BigMul() function, ensuring unbiased randomization for shuffling tasks. Throughout the process, Andante enhanced code maintainability by adding detailed comments explaining the RNG logic and Fisher-Yates algorithm, resulting in clearer documentation and more robust, maintainable software development practices.
June 2025 monthly summary for Cysharp/ZLinq. Focused on RNG/shuffle performance and reliability, delivering a refactor to use Xoshiro256** for Shuffle() and PartialShuffle(), and fixing a BigMul() issue that could bias RNG used by shuffling. Added clarifying comments on RNG logic and Fisher-Yates implementation. Resulted in faster shuffles, more reliable randomization, and improved maintainability with explicit documentation.
