public class ImFreeFormulaDilution extends ImPostulate
The "free-formula dilution" postulate for inconsistency measures: Removing a formula not participating in any minimal inconsistent set does not make the inconsistency value larger.
This postulate is a weaker version of "free formula independence" and is intended to be used with normalized inconsistency measures (which may not fulfill free-formula independence in some cases).- Author:
