JQSakaJoo/Population-optimization-algorithms-MQL5 ? reverse-engineered prompt

Build me a clean MQL5 library of population based optimization algorithms for MetaTrader.

I want the project to include the algorithms already listed in the repo, organized in a way that makes them easy to run, compare, and reuse for optimization problems. Please make the code easy to browse, with a simple common interface for each algorithm so they can all solve the same kind of minimization task. If some of the algorithms need example inputs or a sample objective function, add a small demo so I can see how to use them right away.

Please also tidy up the structure a bit, add short comments where it helps, and make sure the code is consistent across the different implementations. If you need to check any current MQL docs or best practices, go ahead and look them up online.
