[tlaplus] Re: Using TLC to model check "rule-based expert systems"

[Ron Pressler <ron.pressler@xxxxxxxxx>]

I believe conflicting rules would either result in no behaviors (equivalent to FALSE, i.e. you can verify Spec => FALSE) or in a deadlock, which you can detect with liveness. But the main idea is to express the specification not as a state machine, but as a conjunction of state machines, each corresponding to a rule ("conjoined specifications"). Not generally recommended, but might be useful.

Thanks, I’ll take a closer look tomorrow. Does this have some mechanism for detecting inconsistent/conflicting rules?
