hello michal,
congratulations on slaying the monster. the 5^4 is truly frightening to
behold and i'm always impressed when someone goes up against it. i've
added your latest accomplishment to the hall-of-fame. i'm cc'ing the
group here as i'm sure everyone will be interested in your experience
and in the answers to the questions you ask.
i'm glad that you found the java version helpful in this task. i'm sorry
that you needed macros to finish it because then i could have added you
to the first table as the 1st no-macro 5^4 and not had to create a
completely new table! seriously that's not a big deal and i knew i would
have to do it before too long anyway. (note to everyone: the 1st
no-macro 5^4 is still up for grabs!)
i'm not surprised that you say the smaller puzzles look like child's
play. so are you ready to join the 1st 4D speed solving contest? we only
need 3 people, and if you join i think we may have enough contestants.
regarding java macro support, this feature remains to be ported but i'm
not familiar with the c++ code and after a month of work to get to this
point i needed a break and hopefully a little help.
i'm slightly surprised that you were able to pick up your work with the
linux version since the file format is not backwards compatible but i am
glad that it worked for you.
regarding larger puzzles, the problem is that they take up exponentially
enormous amount of memory. i just tested and found that i could create
an 8^4 puzzle on a machine with 2GB RAM but it failed at 9^4. the
biggest problem with offering these huge puzzles is that parts of the
code are set up for the worst case so that offering larger puzzles would
drastically increase the memory requirements of all users. with effort,
that could be redesigned so that only users attempting to use huge
puzzles would require the memory but that will require someone suitably
motivated to do the work.

Congratulation Kirfo!
I've knew you will do this ;) Please have mercy and don't ask about 6^4 ;)
If you start solving it I would have to solve it too ;))) Maybe after two
moths from now?;)
Melinda I must say you did great job with java version.(I can't wait for
macros!).
(I don't like only this auto-rotation. (It starts to spin a litlle bit too
easy). Autorotation is good but it must take more effort to start spinning).
Lately I went under linux and tried "hyperspeedsolving" AGAIN.
I started from 45 minutes...Next there were some solves with 35 minutes.
I've changed some macros ( I use 17) and here my latest results:
30:10,30
33:48,20
31:31,72
28:55,59
28:45,51
As you can see I managed with 30 minutes barier
(Will be there unofficial ranking with fastest solution?)
I must think something new for corners (there was time (few months ago) I
solve this stage in 4-5 minutes..but now it takes me 10 min!!!!
In last attempt I did:
central crosses in [2 min]
face croses in [17 min]
corners in [10 min]
-------------------------------------------
Anyway
First Time Competition is very close to happend :)
We have got in Poland some 4D cubists for example:
Michel Wizner,
Tomek Piotrowski
and me
(we know each other)
Once we even talk about this but Tomek have a little time now...
I think Michal after 4^5 and 5^4 is ready and for hyperspeedsolving and in
few days he probably try this.
So much from me.
Best regards,
Remigiusz Durka
Ps. Guy where is your 5^4 solution? ;-P
