[tlaplus] Re: How to check properties on models with huge numbers of behaviours

While large sets can cause performance problems, it's rare for an algorithm to be correct for a set of 3 elements and not for a set of 1000 elements.

In my specification at each Next step I have something like:

\E i \in Set where the set can have up to 1000 elements (no symmetry)

This causes a lot of branching so there are too many states for the model checker to find even if I let it run for years.

Is there any TLA+/TLC trick to solve this? If not do you know any model checker that could handle this? (l have heard about translating TLA+ to B to check with ProB but I'm not sure if it would help)

Thank you,
