Computing Boston and TTC in Python
I found one implementation of TTC in python at http://www.dreamincode.net/forums/topic/377004-algorithmic-game-theory-top-trading-cycle-procedure/?ref=dzone.

However, it does not seem to include the two additional features I was mentionning.

With of without these two features : I would still love to hear about more implementation of TTC, and about implementations of Boston.
