    Does anyone have resources on learning modelling for formal verification? (Does not have to be in Lean)

    ... somewhat disappointed the guy is now associated with AWS. I guess I was hoping for a non-profit organization.

    While learning and applying formal verification in the context of using AI agents, what I feel is that sometimes it's hard to express my own thoughts as formal verification. But more than that, I doubt whether formal verification being done correctly actually solves the phenomenon of AI spinning in circles on a specific task.

    For example, I want to eat chicken, so I try formally verifying "chicken dish," and every time GPT or Claude starts digging into the origin of the sauce in the chicken dish or the breed of the chicken. Then the chicken dish never gets finished and never makes it to dinner, and instead I gain deep knowledge about the origin of chickens.

    Of course, I know that formal verification has liveness — meaning that there must be progress in the work is also part of formal verification — but the AI judges that learning the origin of the chicken counts as progress too. Yet it ends up doing work that it actually shouldn't be doing.

    Personally, while organizing these AI anti-patterns, I feel that when you formally verify one condition, verification of another condition gets weakened, and within that phenomenon I sense the AI spinning in circles again. In the end, I end up going through the process of reading and merging everything one by one myself, and I want to know whether this is something only I experience.

      A sufficiently powerful agent with sufficiently long horizon task finishing ability will first invent the universe from scratch and only then will it finish your chicken dish.

        It seems you've summarized my problem properly. Haha.

      Your example is not something that can be formally verified.

        What I meant in my comment is that when you use formal verification to verify AI, it passes formal verification, but even if it passes that formal verification, the AI still can’t complete the task. The original article also talks about the importance of specifications in the AI era, but my point is that even if it passes formal verification, the AI still has problems. I’m not sure whether I misunderstood the original.

      You seem to be using "formal verification" with a non-standard meaning.

      > I feel that when you formally verify one condition, verification of another condition gets weakened

      In standard formal verification there is no problem here: you formally verify the composite "condition_1 AND condition_2"

        The problem I often run into is this. It’s not formal verification, but I create a UML diagram to lay out the whole skeleton first. There are usually open-source architecture books, so I take it from there.

        Then it should implement the whole UML skeleton, right? But it goes like this: halfway through, at some point, it says, “This algorithm is too slow? Hmm... I need to make it faster,” and tries local optimization, so sometimes I don’t get the result I want—that is, an MVP that at least runs.

        I know the overall goal clearly, but there’s a problem where it gets obsessed with a specific subgoal or keeps expanding that subgoal.

          Can you try to get it to only specify interfaces first? Then tests, the write code to implement

        I think my English is a bit lacking, so I didn't explain my situation well enough.

        The main point is not that everything is solved if you specify all the conjunction conditions and prove that those conjunction conditions are correct. Rather, the key point is that in that process, the agent keeps expanding subgoals.

        For example, two proofs, P1 and P2, are carried out, but they proceed in a way that diverges from the actual progress of the work. That is, you can prove things like "P1: the chicken is safe" and "P2: the origin of this sauce is trustworthy," but combining these does not make a chicken dish.

        In other words, the proof logic holds, but my actual task doesn't get solved. I'm questioning how to solve this problem. It's frustrating that I'm not a native English speaker at times like this. I'm sorry for causing a misunderstanding.

        For example, it goes like this.

        I proved P1 and P2. But then it creates P1.1. It goes and finds information from an agency certifying that this chicken is safe, and puts that in. Then it starts creating P2.1 as well. The origin of this sauce is trustworthy, but maybe there’s a better one somewhere?

        It goes on like that.
