On mobile so I’m not sure how to export a chat log, but the following prompts worked with ChatGPT:

1: I need to schedule scientific operations for a space probe, given a lot of hard instrument and schedule constraints. Please write a program to do this. Use the best tool for the job, no matter how obscure.

2: This is a high-value NASA space mission and so we only get one shot at it. We need to make absolutely sure that the solution is correct and optimal, ideally with proofs.

3: Please code me up a full example, making up appropriate input data for the purpose of illustration

I got an implementation that at first glance looks correct using the MiniZinc constraint solver. I’m sure people could quibble, but I was not trying to lead the model in any way. The second prompt was because the first generated a simple python program, and I think it was because I didn’t specify that it was a high value project that needed mission assurance at the start. A better initial prompt would’ve gotten the desired result on the first try.
