What we do is give the first scan (which we don't in advance what it is) a

quota of N[1] iterations. We choose the scan that solves the most boards

in this time, and limit it to the maximal number of iterations in which it

will solve all these boards.

We then update the database by removing all these boards, and subtracting

N[1]~ iterations from the iterations count of all the other boards for

this scan. We then repeat the process for an extra N[2] iterations, and so

forth until all boards are solved.

I can run this algorithm for any given { N[i] | 1 <= i < inf } vector and

receive the optimal result for it.
