(MATH) We show that the Minimum Vertex Cover problem is NP-hard to approximate to within any factor smaller than $10\sqrt{5}-21 \approx 1.36067$, improving on the previously known hardness result for a $\frac{7}{6}$ factor.

TLDR
A stronger result is shown, namely, that, based on the same conjecture, vertex cover on k-uniform hypergraphs is hard to approximate within any constant factor better than k.

Approximation hardness of edge dominating set problems

TLDR
It is NP-hard to approximate the solution of both problems to within any constant factor smaller than 7-6, the first interesting explicit lower bounds on efficient approximability for two closely related optimization problems in graphs.

Using the FGLSS-Reduction to Prove Inapproximability Results for Minimum Vertex Cover in Hypergraphs

TLDR
It is shown that Approximating the size of the minimum vertex cover in O(1)-regular hypergraphs to within a factor of 1.99999 is NP-hard.

Approximation Hardness of Minimum Edge Dominating Set and Minimum Maximal Matching

TLDR
It is NP-hard to approximate the solution of both problems to within any constant factor smaller than 7/6, and the result extends with negligible loss to bounded degree graphs and to everywhere dense graphs.

Super-polynomial approximation branching algorithms

TLDR
It is shown that moderately exponential and/or parameterized time approximation schemata can be derived for broad classes of combinatorial optimization problems via a well-known technique widely used for deriving exact algorithms, namely the branching tree pruning.

Approximation Resistance by Disguising Biased Distributions

TLDR
It is shown that the gap problem of some 3-XOR is NP-hard and can be solved by running Charikar\&Wirth's SDP algorithm for two rounds and the author proves that P=NP.

Improved NP-Inapproximability for 2-Variable Linear Equations

TLDR
An instance of the 2-Lin(2) problem is a system of equations of the form "xi + xj = b (mod 2)" in which it’s possible to satisfy all but an C e fraction of the equations.

Approximating clique is almost NP-complete

The computational complexity of approximating omega (G), the size of the largest clique in a graph G, within a given factor is considered. It is shown that if certain approximation procedures exist,

Some Further Approximation Algorithms for the Vertex Cover Problem

TLDR
This paper describes an approximation algorihm for the vertex cover problem which has a worst case ratio strictly smaller than 2 for graphs which don't have too many nodes and presents algorithms which improve in the case of degree bounded graphs the worst case ratios known up to now.

TLDR
The reductions used to prove Max Clique cannot be approximated in polynomial time within n1-Ɛ, for any constant Ɛ > 0, unless NP = ZPP are extended and combined with a recent result of Samorodnitsky and Trevisan.

TLDR
