Dec 31, 2021 · If you choose the importance distribution (q) to be proportional to f(x)p(x), ie, ρ(x):=f(x)p(x)/μ, you achieve a zero variance estimator.

The cross-entropy (CE) method is a Monte Carlo method for importance sampling and optimization. It is applicable to both combinatorial and continuous problems.
