The main parameter defining the efficiency of this method is how quickly the random walk mixes (converges to the stationary distribution). Prof. Anari from Stanford University gave a series of lectures on using log concave polynomials in analysis of random walks to sample and count bases of a matroid. The results have resolved multiple conjectures in combinatorics, probability theory and algorithms.
