This document provides an overview of matroid intersection and some applications. it begins by defining matroid intersection as the common independent sets of two matroids on the same ground set. The paper presents faster algorithms for the matroid intersection problem, improving time complexity significantly. an exact algorithm with independence oracle runs in o (nr log r • t ind) time, enhancing previous o (nr • t ind) results. Abstract: in this paper we consider the classic matroid intersection problem: given two matroids m 1 = (v, i 1 ) and m 2 = (v, i 2 ) defined over a common ground set v , compute a set s ∈ i 1 ∩ i 2 of largest possible cardinality, denoted by r. Given our rank approximation to the matroid intersection problem. exact algorithm result above, it is natural to wonder if one can obtain faster approximation algorithms. This can thus be viewed as a weighted matroid intersection problem and we could use the full machinery of matroid intersection algorithms and results. however, here, we are going to develop a simpler algorithm using notions similar to the hungarian method for the assignment problem.
