A $4/3$ -Approximation Algorithm for the Minimum $2$ -Edge Connected Multisubgraph Problem in the Half-Integral Case

S. Boyd, J. Cheriyan, R. Cummings +4

Given a connected undirected graph $G ˉ$ on $n$ vertices, and non-negative edge costs $c$ , the 2ECM problem is that of finding a $2$ -edge~connected spanning multisubgraph of $\…

An Improved Approximation Algorithm for the Matching Augmentation Problem

J. Cheriyan, R. Cummings, J. Dippel +1

We present a $\frac{5}{3}$ -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 ze…
