Maybe can directly call:

CGAL::Euler::collapse_edge()
https://doc.cgal.org/latest/BGL/group__PkgBGLEulerOperations.html#ga5d15eb83f797b8f91e23e8e9ceec78c9

if the edge satisfy the link condition

CGAL::Euler::does_satisfy_link_condition()

https://doc.cgal.org/latest/BGL/group__PkgBGLEulerOperations.html#ga2d19a3573640a9abb28885425bfd9f40

Hi MaelRL,

I had a question similar to this example. As in this example, it defined the
edges as a constrained edge that will not be removed in the simplification
process.

https://doc.cgal.org/latest/Surface_mesh_simplification/Surface_mesh_simplification_2edge_collapse_constrain_sharp_edges_8cpp-example.html

I have to do something opposite. I have to define some edges that has to be
removed in the simplification process. Is there any function that can define
the edges as removed?

Regards
Shrabani Ghosh
