Similarly, the derivative of base vector
with respect to the arc-length coordinate could be given by the cross product of the curvature and base vectors
In the mutation operator of most DE variants, a mutant vector can be treated as the lead individual to explore the search space and generated by adding a difference vector to a base vector
Three other parents are used to generate each trial vector; the base vector
and two difference vectors.
The imaginary 3D base vector
i of the quaternionic number space is the imaginary base number of the complex number space.
When applied to a base vector
, that is rotating around the Z axis together with the yarn, this equations gives
c] is period of carrier signal, which determines the discreetness of [phi] change, [theta] is angle between the first base vector
Dot products of the base vector
give a set of symmetric numbers which are called metric coefficients.
A DE variant is usually marked as DE/x/y/z, where x denotes how the differential mutation base is chosen, y denotes the number of vector differences added to the base vector
and z indicates the crossover method.

Cartique Mapping is the flagship base vector
