Comment:
The Steiner tree problem [0] is NP-hard and a heuristic algorithm is used
in this module so the result may be suboptimal. The implemented algorithm
needs quite a lot of memory in order to determine a good (not necessarily
optimal) solution. This is not a bug but inherent to the algorithm used by
the module. There may be less memory-intensive solutions. Changing type to
enhancement.
