The concept SimplicialComplexForRips describes the requirements for a type to implement a simplicial complex, that can be created from a Rips_complex. The only available model for the moment is the Simplex_tree.

Expands a simplicial complex containing only a graph. Simplices corresponding to cliques in the graph are added incrementally, faces before cofaces, unless the simplex has dimension larger than max_dim or block_simplex returns true for this simplex.
- Parameters
-
| [in] | max_dim | Expansion maximal dimension value. |
| [in] | block_simplex | Blocker oracle. Its concept is bool block_simplex(Simplex_handle sh) |
The function identifies a candidate simplex whose faces are all already in the complex, inserts it with a filtration value corresponding to the maximum of the filtration values of the faces, then calls block_simplex on a Simplex_handle for this new simplex. If block_simplex returns true, the simplex is removed, otherwise it is kept.
