Solid – A comprehensive gradient-free optimization framework in Python

In plain words

Solid is a Python framework for gradient-free optimization, meaning it finds optimal solutions without requiring derivative calculations. It's designed for developers and researchers who need to optimize functions where gradients are unavailable, expensive to compute, or unreliable. The framework provides comprehensive tools for this type of optimization problem, making it useful for black-box optimization, hyperparameter tuning, and other scenarios where traditional gradient-based methods don't apply.

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
