Dynamic importance sampling for uniformly recurrent markov chains [PDF]

open access: yes, 2005
Importance sampling is a variance reduction technique for efficient estimation of rare-event probabilities by Monte Carlo. In standard importance sampling schemes, the system is simulated using an a priori fixed change of measure suggested by a large ...
