The technique went under the name ‘dynamic programming’,
Grace Lindsay • Models of the Mind
In a graph, the number of nodes is called the "order" (in the square example, INI = 4), and the number of edges is called the "size" ( I E I = 4).
Alexander R. Galloway • The Exploit: A Theory of Networks (Electronic Mediations)
Hence all mathematical derivation can be viewed simply as change in representation,
Herbert A. Simon • The Sciences of the Artificial
Applying these two rules repeatedly to every node in the network is called belief propagation.
Judea Pearl, Dana Mackenzie • The Book of Why

Differential geometry is all about constructing things which are independent of the representation
