Reuse Skolem terms for repeated existential variables - #807
Merged
Conversation
Skolemization previously created a new function for every occurrence of an existential variable. This incorrectly allowed equal occurrences to denote different values. Reuse one Skolem term per existential variable, retain transformed rules, and add a regression test covering repeated variables across head atoms.
