Testing gemini 2.5 pro with a project, A* algorithm to find the most optimal for a high-speed train (optimizing for grades, turn radiuses, multi objective optimization)

doing a consistent job, except literally messing up syntax a lot (tries to squeeze all of the code into 1 line)
it takes patience but it's quite helpful with ideas, the problems and questions you have.

optimising the pathfinding right now, it says failed at the top because it had hit the max node limit for a high quality path.
