What is efficient sampling?
Sampling efficiency is a measure of the optimality of a sampling strategy. A more efficient sampling strategy requires fewer simulations and less computational time to reach a certain level of accuracy. The efficiency of a sampling strategy is highly related to its space-filling characteristics.
How is importance sampling based on a simple technique?
Importance sampling is based on a simple technique that allows to compute expected values in many different but equivalent ways. The next proposition shows how the technique works for discrete random vectors. Proposition Let be a discrete random vector with support and joint probability mass function .

How is importance sampling used in Monte Carlo integration?
Importance sampling is a variance reduction technique used to reduce the variance of the approximation error made when approximating an expected value with Monte Carlo integration.
