Hi Mauricio
Nice to see you back and thanks for uploading your solver again.
I've tested it on your website and it's as fast as I remembered.
Can you confirm my (maybe erroneous) souvenir that it is based on dancing links?

I believe it is bugged somewhere, but now I do not have the time or knowledge to correct it; be aware that I never got to prove that the implementation of whips works, since I did not understand why it works, but it seems to work, it was only a modification of the implementation of braids.
The implementation of braids may be bugged, since for some puzzles, its g-braid rating is bigger that its braid rating, and that is something I believe should not be possible.

Sure, the gB rating can't be higher than the B rating.

Hi denis_berthier:
Can you test this puzzle?My need to use large memory mode.Can you test this puzzle? My solver needs to use large memory mode. Means the total nodes are more than 20000.

.6.7..3.......5..98...3..1..3.8..4....4..1..79..5...2..4...72..2..9.......8.5..6.

Not sure what you want me to test. Here are the whip and g-whip solutions (no other rules activated), starting form the resolution state after Singles and whips[1]:

As you can see, 3 g-whips are found, but they do not modify the rating: gW = W.

As for the resolution times and memory (using the simplest-first strategy), the solution with g-whips is 15 times slower and it takes 6.7 times more memory than with whips only.
I can't say anything about your nodes count, as CSP-Rules is not based on nodes.

This one has B-rating=29 and gB-rating=28, which surprises me, since I would think that the gB-rating would be a lot lower for difficult puzzles that the B-rating.

The only thing we know is, in unbiased stats, W=gW=B=gB for 99.5% of the puzzles - but the mean values are quite low.
Puzzles with so high ratings have probability close to 0 and we know strictly nothing about the difference of their ratings.

[yzfwsf]

#153 from Top 1465, ER=4.0, But this puzzle cannot be solved by a whip or even a braid alone. It can be solved with gWhip[9] or gBaid[8]. Mauricio's js solver give rating gBraid[12].

This puzzle is the one with the highest gB rating I have found so far. gB rating=g-Braid[29]

Great.
It should be mentioned that the puzzle is not in T&E(1), so that its B rating is infinite.

Also, when you post a puzzle, could you systematically mention its origin?

The B rating of a puzzle not solvable by braids is infinite. The question makes no sense.

Again: who's the author of the gB29 puzzle: 000009007004030010080100000001000002030080040700000500000005600090040030200900000 ER9.9/9.9/9.3

Mauricio's puzzle is also in T&E(Single,2), but gB-Rating=2

Don't you look at the original post? I have added notes on the author and source.
