Faster FPRAS for the Permanent via Restricted Poincaré Inequalities and Coupled Flows

Xiaoyu Chen, Eric Vigoda, Xiongxin Yang

The permanent of an matrix equals the number of perfect matchings in the bipartite graph with edges defined by . Jerrum, Sinclair, and Vigoda (2004) presen…

Counting and Sampling Labeled Chordal Graphs in Polynomial Time

Ursula Hebert-Johnson, Daniel Lokshtanov, Eric Vigoda

We present the first polynomial-time algorithm to exactly compute the number of labeled chordal graphs on vertices. Our algorithm solves a more general problem: given and $…

Optimal Mixing via Tensorization for Random Independent Sets on Arbitrary Trees

Charilaos Efthymiou, Thomas P. Hayes, Daniel Stefankovic +1

We study the mixing time of the single-site update Markov chain, known as the Glauber dynamics, for generating a random independent set of a tree. Our focus is obtaining optimal co…

Complexity of High-Dimensional Identity Testing with Coordinate Conditional Sampling

Antonio Blanca, Zongchen Chen, Daniel Štefankovič +1

We study the identity testing problem for high-dimensional distributions. Given as input an explicit distribution , an , and access to sampling oracle(s) for a hi…
