enumeration; number of bases; matroid; polynomial randomised approximation scheme
The exact enumeration of the number of bases of a matroid is known to be \(\#\)-hard and even a good approximation is impossible if deterministic methods can only be used. The authors show that a polynomial randomised approximation scheme exists for a large class of matroids.
