Update nodes in topological order

[samevision]

Hello,

I want to build a node editor that works like the shader editor or the geometry node editor of Blender. So I have an acyclic directed graph. Cycles are not present.

To put the nodes in an appropriate order, I sorted topologically with d3-dag according to zherebko.

Because of this order, I now want to ensure that not all nodes are recalculated when this is not necessary. Only the values of the nodes should be updated, which are also dependent on the respective change.

What is the best way to implement this?

Many greetings
