An algorithmic study of relative cardinalities for interval-valued fuzzy sets
We define generalised relative cardinality for IVFS using different t-norms. We study properties of such relative cardinality especially as a subsethood measure. We construct efficient algorithms to compute such relative cardinality for IVFS. We discuss practical implementation and applications of proposed algorithms.
