Such feature is not implemented mainly because there may be
exponentially many basic solutions. Besides, unlike LP case, it would be
quite difficult to enumerate all integer feasible/optimal solutions.

Nevertheless, imagine that you have obtained all the feasible or optimal
solutions. In which way would you use them?
