Member Enumeration Documentation

enum Ordering

Enumerator

Factors

The variates with the best quality will be used for the evolution of the first factor.

Steps

The variates with the best quality will be used for the largest steps of all factors.

Diagonal

A diagonal schema will be used to assign the variates with the best quality to the most important factors and the largest steps.
