The main technique used in algorithm design for approximating #P-hard counting problems is the Markov chain Monte Carlo method. At the heart of the method is the study of the convergence (mixing) rates of particular Markov chains of interest. In this paper we illustrate a new approach to the coupling technique, which we call path coupling, for bounding mixing rates. Previous applications of coupling have required detailed insights into the combinatorics of the problem at hand, and this… 
Rapidly Mixing Markov Chains: A Comparison of Techniques (A Survey)
It is proved that for a large class of Markov chains canonical paths does capture rapid mixing, which motivates the question of whether Coupling can be made to work whenever the chain is rapidly mixing.
Canonical Paths for MCMC: from Art to Science
The task of designing canonical paths for MCMC is reduced to solving a set of linear equations, which can be automatically done even by a machine, and fully polynomial-time randomized approximation schemes (FPRAS) for counting the number of b-matching with b ≤ 7 and b-edge-cover with b ≥ 2 are obtained.
Rapid mixing through decomposition and induction
The thesis concludes with the treatment of a novel decomposition method and its application to bounding the convergence rate of a random process on finite, complete d-ary trees.
An Extension of Path Coupling and Its Application to the Glauber Dynamics for Graph Colorings
It is shown that the Glauber dynamics has O(n log(n) mixing time for triangle-free $\Delta$-regular graphs if k colors are used, where $k\geq (2-\eta)\Delta$, for some small positive constant $\eta$.
Disjoint Decomposition of Markov Chains and Sampling Circuits in Cayley Graphs
A new version of the decomposition theorem is presented where the pieces partition the state space, rather than forming a cover where pieces overlap, as was previously required, which is more natural and better suited to many applications.
Delayed path coupling and generating random permutations
The main result is that distributed mixing needs log n simple point-to-point communication rounds to generate a permutation almost uniformly at random.
Approximating graph-theoretic counting problems with Markov chain simulation
In graph theory, it is hard to find exact answers for certain counting problems efficiently. For example, counting the number of proper k-colourings or independent sets on a graph are hard to do
Perfect sampling using bounding chains
In Monte Carlo simulation, samples are drawn from a distribution to estimate properties of the distribution that are too difficult to compute analytically. This has applications in numerous fields,
Markov chains for sampling matchings
A lemma is developed which obtains better bounds on the mixing time in this case than existing theorems, in the case where β = 1 and the probability of a change in distance is proportional to the distance between the two states.
Fast sampling and counting 𝑘-SAT solutions in the local lemma regime
The main technical contribution is to use the local lemma to bypass the connectivity barrier in traditional Markov chain approaches, which makes the well developed MCMC method applicable on disconnected state spaces such as SAT solutions.


Faster random generation of linear extensions
Path Coupling, Dobrushin Uniqueness, and Approximate Counting
In this paper we illustrate new techniques for bounding the mixing rates of certain Markov chains. Whereas previous techniques have required extensive insight into the combinatorics of the problem in
Beating the 2Δ bound for approximately counting colourings: a computer-assisted proof of rapid mixing
This work proposes a novel computer-assisted proof technique to establish rapid mixing of a new “heat bath” Markov chain on colourings using the method of path coupling and outlines an extension to 7-colourings of triangle-free 4-regular graphs.
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.

For a large number of natural counting problems for which there was no previous indication of intractability, that they belong to the class of computationally eqivalent counting problems that are at least as difficult as the NP-complete problems.
Graph orientations with no sink and an approximation for a hard case of #SAT
All of the major combinatorial problems associated with sink-free graph orientations are considered: decision, construction, listing, counting, approximate counting and approximate sampling.

A simple but very general Monte-Carlo technique for the approximate solution of enumeration and reliability problems and several applications are given.
A random polynomial-time algorithm for approximating the volume of convex bodies
The proof of correctness of the algorithm relies on recent theory of rapidly mixing Markov chains and isoperimetric inequalities to show that a certain random walk can be used to sample nearly uniformly from within K within Euclidean space.
Approximately counting up to four (extended abstract)
We presenta fully-polynomial scheme to approximate the number of independentsets in graphswith maximum degree four. In general, for graphswithmaximum degree A ~ 4, the scheme approximates a weighted
