Show HN: Vibesolve.ai – Turn plain English into Timefold code

- **Timefold** is an open-source AI solver for constraint satisfaction and optimisation problems (scheduling, route planning, staff rostering, etc.). It evolved from the well-known project OptaPlanner after Red Hat dropped support for it. - **Mathematical optimisation** (or "operations research") is the field of finding the best possible solution under constraints — e.g., the shortest delivery route, the most efficient hospital shift roster. Traditional optimisation code is hard to write and debug. - VibeSolve aims to let developers describe an optimisation problem in plain English and have an LLM generate Timefold solver code. It is still experimental: useful for fast prototypes, not for production. - The project is notable because LLMs usually struggle with optimisation logic; the creators claim VibeSolve outperforms asking ChatGPT directly for Timefold code. It addresses a specific pain point where natural-language-to-code tools have been weak.
