The Complexity of Computing the Sign of the Tutte Polynomial (and Consequent #P-hardness of Approximation)

- Computer Science, MathematicsICALP
- 2012

This work completely resolve the complexity of computing the sign of the chromatic polynomial -- this is easily computable at q=2 and when q≤32/27, and is NP-hard to compute for all other values of the parameter q.

Exponential Time Complexity of the Permanent and the Tutte Polynomial

- Computer Science, MathematicsICALP
- 2010

The Exponential Time Hypothesis is relaxed by introducing its counting version, namely that every algorithm that counts the satisfying assignments requires time exp(Ω(n), and the sparsification lemma for d-CNF formulas is transferred to the counting setting, which makes #ETH robust.

ON THE QUANTUM COMPLEXITY OF EVALUATING THE TUTTE POLYNOMIAL

- Mathematics

We show that the problem of approximately evaluating the Tutte polynomial of triangular graphs at the points (q, 1/q) of the Tutte plane is BQP-complete for (most) roots of unity q. We also consider…

Complexity and Approximability of the Cover Polynomial

Under the reasonable complexity assumptions RP ≠ NP and RFP ≠ #P, a succinct characterization of a large class of points at which approximating the geometric cover polynomials within any polynomial factor is not possible is given.

Matroids, Complexity and Computation

- Mathematics, Computer Science
- 2013

The hierarchy of all matroid descriptions is created and studied and generalize this to all descriptions of countable objects and shows that it is #P-complete to count the number of bases of matroids representable over any infinite fixed field or finite fields of a fixed characteristic.

The Complexity of the Cover Polynomials for Planar Graphs of Bounded Degree

- MathematicsMFCS
- 2011

It is shown that almost the same dichotomy holds when restricting the evaluation to planar graphs, and algorithms that allow for polynomial-time evaluation of the cover polynomials at certain new points by utilizing Valiant's holographic framework are provided.

The BQP-hardness of approximating the Jones Polynomial

- MathematicsArXiv
- 2006

The universality proof of Freedman et al (2002) is extended to ks that grow polynomially with the number of strands and crossings in the link, thus extending the BQP-hardness of Jones polynomial approximations to all values to which the AJL algorithm applies, proving that for all those values, the problems are B QP-complete.

- 2022

We study the complexity of approximating the partition function of the q-state Potts model and the closely related Tutte polynomial for complex values of the underlying parameters. Apart from the…

We show that determining the Jones polynomial of an alternating link is #P-hard. This is a special case of a wide range of results on the general intractability of the evaluation of the Tutte…

Polynomial Time Randomised Approximation Schemes for Tutte-Gröthendieck Invariants: The Dense Case

A general technique is developed that supplies fully polynomial randomised approximation schemes for approximating the value of T(G; x, y) for any dense graph G, that is, any graph on n vertices whose minimum.

A contribution to the theory of chromatic polynomials

Summary Two polynomials θ(G, n) and ϕ(G, n) connected with the colourings of a graph G or of associated maps are discussed. A result believed to be new is proved for the lesser-known polynomial ϕ(G,…

The Tutte polynomial

$q$-Matroids are defined on complemented modular support lattices. Minors of length 2 are of four types as in a "classical" matroid. Tutte polynomials $\tau(x,y)$ of matroids are calculated either by…

On Unapproximable Versions of NP-Complete Problems

- Computer Science, MathematicsSIAM J. Comput.
- 1996

All of Karp's 21 original $NP$-complete problems have a version that is hard to approximate, and it is shown that it is even harder to approximate two counting problems: counting the number of satisfying assignments to a monotone 2SAT formula and computing the permanent of $-1, $0, $1$ matrices.

The complexity of approximate counting

- Computer Science, MathematicsSTOC

The complexity of computing approximate solutions to problems in #P is classified in terms of the polynomial-time hierarchy (for short, P-hierarchy) in order to study a class of restricted, but very natural, probabilistic sampling methods motivated by the particular counting problems.

It is shown that the problem becomes NP-hard as soon as $k=3$, but can be solved in polynomial time for planar graphs for any fixed $k$, if the planar problem is NP- hard, however, if £k$ is not fixed.

This work describes and investigates a third class of counting problems, of intermediate complexity, that is not known to be identical to (i) or (ii), and can be characterised as the hardest problems in a logically defined subclass of #P.
