The method approximates the optimal importance sampling estimator by repeating two phases: [1] Draw a sample from a probability distribution.
The order crossover goes back to Davis [1] in its original form and is presented here in a slightly generalized version with more than two crossover points. It transfers information about the relative order from the second parent to the offspring. First, the number and position of the crossover points are determined randomly.
An N of 1 trial (N=1) is a multiple crossover clinical trial, conducted in a single patient. [1] A trial in which random allocation is used to determine the order in which an experimental and a control intervention are given to a single patient is an N of 1 randomized controlled trial.
