Set intersection oracle

A set intersection oracle (SIO) is a data structure which represents a collection of sets and can quickly answer queries about whether the set intersection of two given sets is non-empty. The input to the problem is n finite sets. The sum of the sizes of all sets is N (which also means that there are at most N distinct elements). The SIO should quickly answer any query of the form: "Does the set Si intersect the set Sk"? (Wikipedia).

What is an Intersection? (Set Theory)

What is the intersection of sets? This is another video on set theory in which we discuss the intersection of a set and another set, using the classic example of A intersect B. We do not quite go over a formal definition of intersection of a set in this video, but we come very close! Be su

Set Intersection Using Venn Diagrams

The set intersection, another fabulous set operation. What is set intersection? The intersection of two sets, A and B, is the set C containing all elements that are in A and B. That is, C contains elements that appear in both A and B (for those of you not familiar with the literal implicat

Power Set of Intersection Equals Intersection of Power Sets | Set Theory

We'll prove that P(A intersect B) = P(A) intersect P(B). That is, the power set of an intersection is the intersection of the power sets! Just as beautiful as we would hope! We prove this the usual way, first proving P(A intersect B) is a subset of P(A) intersect P(B) and then that P(A) in

Given a separation oracle SO for a convex function f that has an integral minimizer inside a box with radius R, we show how to find an exact minimizer of f using at most • O(n(n + log(R))) calls to SO and poly(n,log(R)) arithmetic operations, or • O(nlog(nR)) calls to SO and exp(O(n)) · po

Proportional fairness (also known as 1-fairness) is a fairness scheme for the resource allocation problem introduced by Nash in 1950. Under this scheme, an allocation for two players is unfair if a small transfer of resources between two players results in a proportional increase in the ut
