The Matching Augmentation Problem: A 7/4-Approximation Algorithm
(University of Waterloo, 2019-05-23)We present a 7/4 approximation algorithm for the matching augmentation problem (MAP): given a multi-graph with edges of cost either zero or one such that the edges of cost zero form a matching, find a 2-edge connected ...
