The Mixing of Markov Chains on Linear Extensions in Practice
- MathematicsIJCAI
- 2017
The empirical results suggest that the Markov chain approach to sample linear extensions can be made to scale well in practice, provided that the actual mixing times can be realized by instance-sensitive bounds or termination rules.
A Sequential Importance Sampling Algorithm for Counting Linear Extensions

This technique is based on improving the so-called Knuth counting algorithm by incorporating an importance function into the node selection technique giving a sequential importance sampling (SIS) method, and defines and reports performance on two importance functions.

Approximate sampling from combinatorially-defined sets, using the Markov chain Monte Carlo method, is discussed from the perspective of combinatorial algorithms. We also examine the associated…

This Markov chain provides a way to sample the linear extensions of the poset with a relaxation time bounded above by n2/(n + 2) and a mixing time of O(n2log n) as for the usual random-to-random shuffling.

We show how to combine Fourier analysis with coupling arguments to bound the mixing times of a variety of Markov chains. The mixing time is the number of steps a Markov chain takes to approach its…
Path coupling: A technique for proving rapid mixing in Markov chains
- MathematicsProceedings 38th Annual Symposium on Foundations of Computer Science
- 1997
A new approach to the coupling technique, which is called path coupling, for bounding mixing rates, is illustrated, which may allow coupling proofs which were previously unknown, or provide significantly better bounds than those obtained using the standard method.
An approximation algorithm for random generation of capacities
- Computer Science, MathematicsArXiv
- 2022
This paper proposes the 2-layer approximation method, which generates a subset of linear extensions, eliminating those with very low probability, and shows that this method has similar performance compared to the Markov chain but is much less time consuming.
L ∞ -Discrepancy Analysis of Polynomial-Time Deterministic Samplers Emulating Rapidly Mixing Chains
- Mathematics, Computer ScienceCOCOON
- 2014
A deterministic sampling algorithm based on deterministic random walk, such as the rotor-router model (a.k.a. Propp machine) is proposed, which provides samples with a “distribution” with a point-wise distance at most e from the target distribution, in time polynomial in the input size and e − 1.

Approximate Counting, Uniform Generation and Rapidly Mixing Markov Chains
- MathematicsWG

The general techniques of the paper are used to derive an almost uniform generation procedure for labelled graphs with a given degree sequence which is valid over a much wider range of degrees than previous methods: this in turn leads to randomised approximate counting algorithms for these graphs with very good asymptotic behaviour.
