Sampling-based algorithms, such as the Markov-Chain Monte Carlo (MCMC) approximation of the HJB equation (Kushner and Dupuis,1992;Huynh et al.,2016), rely on The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data. Fermi problems typically involve making justified guesses about quantities and their variance or lower and upper bounds. See more In physics or engineering education, a Fermi problem, Fermi quiz, Fermi question, Fermi estimate, order-of-magnitude problem, order-of-magnitude estimate, or order estimation is an estimation problem designed to teach See more Scientists often look for Fermi estimates of the answer to a problem before turning to more sophisticated methods to calculate a precise answer. This provides a useful check on the results. While the estimate is almost certainly incorrect, it is also a simple calculation … See more • Guesstimate • Dead reckoning • Handwaving • Heuristic • Orders of approximation See more An example is Enrico Fermi's estimate of the strength of the atomic bomb that detonated at the Trinity test, based on the distance traveled by pieces of paper he dropped from his … See more Fermi questions are often extreme in nature, and cannot usually be solved using common mathematical or scientific information.

In the Feynman-α method, first, time-series data of neutron counts (so-called “reactor noise”) are measured for a steady-state subcritical system.
