Irreducible Markov Chains on spaces of graphs with fixed degree-color sequences
Félix Almendra-Hernández, Jesús A. De Loera, Sonja Petrović
We study a colored generalization of the famous simple-switch Markov chain for sampling the set of graphs with a fixed degree sequence. Here we consider the space of graphs with co…
Sampling lattice points in a polytope: a Bayesian biased algorithm with random updates
Miles Bakenhus, Sonja Petrović
The set of nonnegative integer lattice points in a polytope, also known as the fiber of a linear map, makes an appearance in several applications including optimization and statist…
The Spark Randomizer: a learned randomized framework for computing Gröbner bases
Shahrzad Jamshidi, Sonja Petrović
We define a violator operator which captures the definition of a minimal Gröbner basis of an ideal. This construction places the problem of computing a Gröbner basis within the fra…
Markov bases: a 25 year update
Félix Almendra-Hernández, Jesús A. De Loera, Sonja Petrović
In this paper, we evaluate the challenges and best practices associated with the Markov bases approach to sampling from conditional distributions. We provide insights and clarifica…
