A note on Cunningham's algorithm for matroid intersection

Published 8 Apr 2019 in cs.DS | (1904.04129v1)

Abstract: In the matroid intersection problem, we are given two matroids of rank $r$ on a common ground set $E$ of $n$ 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 $O(nr\log^2(r))$ independent oracle calls.
