Within data modelling, cardinality is the numerical relationship between rows of one table and rows in another. Common cardinalities include one-to-one, one-to-many, and many-to-many. Cardinality can be used to define data models as well as analyze entities within datasets. WebThe cardinality constrained monotone submodular maximization problem takes as input a collection of items V, a monotone submodular function f : 2V →R+, and a cardinality constraint b. The goal is to choose a subset of items S ⊆V that maximizes f(S) while ensuring that S ≤b. To show the reduction, we take an instance of the cardinality ...
