Detailed Description

A generic procedure for the computation of chain contraction of a filtered cell complex stored in a file.

This is a complete procedure good for simplicial, cubical, or other complexes. It computes an algebraic topological model. This computation fails if homology is not torsion-free.

Computes an AT model and the homology of a cellular complex.

The cellular complex is read from the given file. Only top-dimensional cells should be listed in the file, or otherwise the filtration may not be generated correctly.
