The author presents improved inapproximability results for three problems: the problem of finding the maximum clique size in a graph, the problem of finding the chromatic number of a graph, and the problem of coloring a graph with a small chromatic number with a small number of colors. J. Hastad's (1996) result shows that the maximum clique size in a graph with n vertices is inapproximable in polynomial time within a factor n/sup 1-/spl epsi// or arbitrarily small constant /spl epsi/>0 unless… Expand
Better Inapproximability Results for MaxClique, Chromatic Number and Min-3Lin-Deletion
TLDR
It is shown that for any constant γ> 0, there is no polynomial time algorithm that approximates these problems within factor $n/2^{(\log n)^{3/4+\gamma}}$ in an n vertex graph, assuming ${\rm NP} \nsubseteq {\rm BPTIME}(2^{log n]^{O(1)}})$. Expand
Super-polylogarithmic hypergraph coloring hardness via low-degree long codes
We prove improved inapproximability results for hypergraph coloring using the low-degree polynomial code (aka, the"short code" of Barak et. al. [FOCS 2012]) and the techniques proposed by Dinur andExpand
Towards optimal lower bounds for clique and chromatic number
TLDR
The reductions used to prove these results are extended and combined with a recent result of Samorodnitsky and Trevisan to show that unless NP ⊆ ZPTIME(2O(log n(log log n)3/2), neither Max Clique nor Min Chromatic Number can be approximated in polynomial time within n1-e(n). Expand
From Gap-ETH to FPT-Inapproximability: Clique, Dominating Set, and More
TLDR
It is shown that both Clique and DomSet admit no non-trivial FPT-approximation algorithm, and the results hold under the Gap Exponential Time Hypothesis (Gap-ETH) which states that no 2^{o(n)}-time algorithm can distinguish between a satisfiable 3SAT formula and one which is not even (1 - c)-satisfiable for some constant c ≈ 0.

Graphs with tiny vector chromatic numbers and huge chromatic numbers
TLDR
The bounds on the sample size improve previous bounds of Goldreich, Goldwasser and Ron (1998) for this problem and analyze "property testing" algorithms that distinguish between graphs that have an independent set of size n/k, and graphs that are "far" from having such anindependent set. Expand
Constant factor approximation of MAX CLIQUE
TLDR
It is shown that MCP can be approximated with a constant factor in polynomial time through approximation ratio preserving reductions from MCP toMAX DNF and from MAX DNF to MIN SAT. Expand
Inapproximability of Maximum Biclique Problems, Minimum k-Cut and Densest At-Least-k-Subgraph from the Small Set Expansion Hypothesis
TLDR
Conditional inapproximability results with essentially optimal ratios for the following graph problems based on the Small Set Expansion Hypothesis are proved: Maximum Edge Biclique, Maximum Balanced Bicles, Minimum k-Cut and Densest At-Least-k-Subgraph. Expand
Ruling Out PTAS for Graph Min-Bisection, Densest Subgraph and Bipartite Clique
TLDR
It is shown that graph min-bisection, densest subgraph and bipartite clique have no PTAS, and a way of certifying that a given polynomial belongs to a given subspace of polynomials is given. Expand
Polynomial integrality gaps for strong SDP relaxations of Densest k-subgraph
TLDR
The results indicate that approximating Densest k-subgraph within a polynomial factor might be a harder problem than Unique Games or Small Set Expansion, since these problems were recently shown to be solvable using neΩ(1) rounds of the Lasserre hierarchy, where e is the completeness parameter in Unique Games and Small Set expansion.
