The following computation takes a lot of time:
{{{
sage: from sage.games.quantumino import QuantuminoSolver
sage: QuantuminoSolver(0).number_of_solutions() # long time (about 30
days)
}}}
but we can make it faster by doing the computation in parallel... This
ticket does this. It is motivated by a question I received from Nicolaas
Neuwahl, the designer of the Quantumino puzzle:
''can you tell me HOW MANY different quantumino-solutions exist?''
The
[http://familygamesamerica.com/mainsite/consumers/productview.php?pro_id=274&search=quantumino
official website] says ''there are over 10.000 potential solutions''.
