Subject: Solving 3^7



Hi guys,

There hasn't been much discussion on high dimensional puzzles, and I haven'=
t solved any puzzle >=3D 4D recently. So I started my attempt to solve 3^7 =
in the last weekend.

Since solving such a complicated puzzle is a somewhat tedious journey, I'd =
like to report my progress. Just now I've solved the 1C, 2C, 3C and 4C piec=
es. I've used 24 hours in total. I guess solving 5C and 6C pieces should be=
the most time consuming steps. I tried my best to find the fastest way to =
solve it but that's what I've got. I can't imagine how Charlie Mckiz solved=
everything in 27 hours. He solved 3^6 first. Maybe he learned and practice=
d some good techniques there. However, I, just like Andrey, skipped 3^6 and=
directly came to 3^7.

I'd like to thank Andrey for telling me how the state of the puzzle is repr=
esented in the log file. Thanks to him, I'm able to automatically track the=
percentage of completion for each type of pieces.

Maybe I need two more weeks till I solve it completely. I hope that day com=
es sooner.

Nan

Phew... I've just solved 3^7!=20

I've used 1.8 million moves to solve it, which is an order of magnitude gre=
ater than what Andrey used. But I'm fine with this number and the strategy =
that I'm using.=20

The duration of the solution is about 47 hours. But at about 45 hours the p=
rogram made a error. It messed up the time of this log file with that of a =
test log file when I switched between them. I don't know why it happened. S=
o eventually the program said that I've used 27 hours. But it should be ~ 4=
5 hours. The duration is similar to that of 120-cell, or the three {3,7} Kl=
ein Quartics combined.=20

The whole thing took me 15 days. So great it's over.

That's awesome Nan, well done!

Ha! This sentiment really reminded me of my feeling after finishing the
3^5. I can only futilely try extrapolate based on 4D and 5D, but maybe the
emotion is somewhat proportional to 3^7/3^5. In other words, an order of
magnitude stronger than what I experienced :)

Cheers,
Roice

Wow, congrads!

I was wondering if you or Andrey could write a tutorial as I really want to=
do at least one 5D puzzle (maybe even a 7D). =C2=A0I found 4D to be too ea=
sy.

Nan, congratulations!=20
So now we have steady rate of one solution of 3^7 every 10 months (2010'0=
7, 2011'05, 2012'03) :) I'll say that it's very good for this kind of puzzl=
e.

15 days look not very long time for me: I spent about two months for my s=
olve. Bug with the time is interesting, but I'll not look for it - let it b=
e this way.

Congratulations again and good luck with future solves :)

Andrey
