PTC introduced Stochastic lattices (random lattices) in Creo Parametric 6.0. This first implementation of the stochastic lattices used Voronoi diagram algorithm. Voronoi is a common algorithm when you want a lattice to conform to bionic shapes.
However, starting with Creo Parametric 188.8.131.52, Delaunay triangulation was introduced. The Delaunay triangulation generates a set of triangles to use as polygons in the model.
To learn more about creating Stochastic lattices using the Delaunay triangulation, refer to this tutorial on PTC Learning Connector

About Punditas AI
PTC has embedded Punditas AI (Artificial Intelligence) Advisor in Creo. Punditas AI Advisor provides real-time guidance as you work in the Creo environment. Information on “how to use” a feature in Creo or best practices for working with Creo are presented within context, removing the need to guess or search for such information. Punditas AI driven content helps you leverage Creo to create your designs faster and with confidence. Check out here
