A 4/3-approximation for Minimum Weight Edge Cover
thesisposted on 17.04.2020 by Steven Alec Gallagher
In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
This paper addresses the minimum weight edge cover problem (MEC), which is stated as follows: Given a graph G= (V,E), find a set of edges S:S⊆E and ∑e∈Sw(e) ∑e∈Qw(e)∀Q: Q is an edge cover. Where an edge cover P is a set of edges such that ∀v∈V v is incident to at least one edge in P. An efficient implementation of a 4/3-approximation for MEC is provided. Empirical results obtained experimentally from practical data sets are reported and compared against various other approximation algorithms for MEC.
