You have the information about what will be collapsed in the visitor.
You are free to assign an id to the edge if needed using a hash map
if needed.

Hi,
I am working on surface_mesh_simplification.
I am referencing here this example.

https://doc.cgal.org/latest/Surface_mesh_simplification/Surface_mesh_simplification_2edge_collapse_visitor_surface_mesh_8cpp-example.html

I want to keep track of the edges are collapsing for further use.
Let's say, in my mesh, there are 10 edges.

I want to use keep trace if edges 5,6,7,8 are collapsing.
if 6 and 7 number edges are collapsed, I want to save the edge numbers.

And after collapsing edges on the first iteration, the ids of the edges
changes from the original mesh?

Thank you.
Shrabani Ghosh
