Excellent work.
I, too, have thought about DLX a lot. It is well known, being
recommended by Knuth, more than once, in the context of
people who need to solve NP-complete problems.
This is part of the general paradigm of solving NP-complete
problems, where you build up a library of very good
If you want to carry out operations on the semiring afore mentioned,
where adding is OR (not XOR) and multiplying is AND, then you can
use floating point arithmetic.
Let Z be 0, and let P be non-zero positive. Then ordinary
multiplication and addition have the following chart
ZZ=Z, ZP=Z, PP=P.

Hi Hector,
I just noticed that the binary downloads for sage-2.10.2 haven't been
updated, just the source code is available.

The following code is fine if 10^17 is replaced by (say) 10^16, so the
underlying cause is probably due to being close to pari's limitations.
But the error message is rather unacceptable! Here gp is yielding an
