Makes sense now. Thanks.

Talk about wasted work. They're only doing TF at the moment, no LL tests.

Believe it or not, I take this as good news. Because when they started, they haven't been doing TF at all and were defiant about that. Under the CaptObvious alias, I've posted some thoughts on their forum. It took a few months for them to switch from denial to anger, ...and finally (good for them) to acceptance.

But why do they continue at all when they surely know about GIMPS and it's massive user base? Do they have someway to not duplicate effort? (They surely know because they know what the other primes are, and it's hard to ignore who found them. Also, posting under CaptObvious can't have helped Why were they angry/in da Nile?)

People take baths in Da Nile because they are about something else besides what they say they are...they have these fragile little things called egos....and they can't bear to admit they wasted some serious effort before Cap'n Obvious came along.

Just because we tell Mr Silverman not to do his number, doesn't mean there's not silliness..

Hehe, I haven't seen this topic till now, but I somehow believe the guy. I was in the same situation sometime in '82-'83, during my high school I wrote a Fortran program which showed that freestyle gomoku is a sure win. That was about 10 years before Victor Allis published his studies. But that was mainly a "curiosity" during that time, in a communist country where people barely had anything to eat, who cared about playing gomoku? :D

But that freestyle gomoku was too easy, I might add. Of course it is a win for black! Modern versions of the game are not computed to the end: e.g. with a swap, six-ers forbidden and the central square restrictions (Sapronov's). "Tito" (by A.Tokarev) is a good AI player; I run it as inside a robot* against human players for years on a certain Russian site.

______
* that is, I wrote the robot which is just some glue code for ten different games; the robot runs 24/7. The game binaries are not written by me, but I had to be familiar with all their quirks. It was a lot of fun for quite a while for me.

Yes, now we know the world war is bad, and we also know the FLT is true. But 20 years ago we did not... Being "too easy" is one, and proving that is sure win is another one. "Being too easy" didn't stop me to win most of the games in highschool even when I was playing white (and all games as black), so "too easy" is relative... Sorry for offtopic. [edit: six-forbidden is also surewin, in just 3 moves more, see Allis's papers, if no other restrictions applies, like in Renju for example. I am a top player of almost all versions, still. Even with more restrictions, as in Renju, with 4x4 and 3x3 forbidden points, black still has surewin, see Renju openings d4 and i7, but all these things were done AFTER that, they are consequence of the fact proven by Allis&co]

Default update

saw the activity on this thread and thought it was time for an update:

M756839 is still three years away!
At current rate, clearing slightly under 14 candidates a day we can expect him to get to M756839 in the middle of 2015. The workrate has been steady for the last few months, and no major slow-ups since whatever happened last summer.

I was going to post at xmas when i was pretty certain M756839 was less than three years away.

However recent progress has been very slow and presently my spreasheet suggests 2 years 350 days from now. Clearly I need a better model.
