A note on Cunningham's algorithm for matroid intersection

Data Structures and Algorithms 2019-04-09 v1

Abstract

In the matroid intersection problem, we are given two matroids of rank rr on a common ground set EE of nn elements and the goal is to find the maximum set that is independent in both matroids. In this note, we show that Cunningham's algorithm for matroid intersection can be implemented to use O(nrlog2(r))O(nr\log^2(r)) independent oracle calls.
