Good day, everybody. In this post, I want to describe what I did this week, June 1-6. I have added the initial implementation of the hill_climbing class. It includes an update function - the main function that changes the required number of threads. To implement this function, I added the Complex class - the base class for working with complex numbers. https://github.com/sapiest/server/commits/10.5-update_threadpool_concurrency The main work is not completed yet, as the algorithm requires adjustments and adaptation in MariaDB environment. Regards, Anton MIkhailenko
