WidPerDim

In the WidPerDim algorithm (Width Per Dimension), the radial basis functions are generalized. Rather than having a single width parameter, a different width in each input factor can be used; that is, the level curves are elliptical rather than circular (or spherical, with more factors). The basis functions are no longer radially symmetric.

This can be especially helpful when the amount of variability varies considerably in each input direction. This algorithm offers more flexibility than TrialWidths, but is more computationally expensive.
