Oh, alright. Fair enough.

 

[TipsterTrickster]

Dang, I also did a bunch of work on it to, I guess I'll have a bit of a head start on Kompetition 3 lol.

Bump. Submitted. Although this Kompetition is incredibly confusing and difficult so my answers to some of them were very basic and pretty dumb if I do say so myself. I know I'm not going to even come close to winning this one. GL to all.

 

[TipsterTrickster]

Submitted! I'm pretty sure I made some errors so I'll probably resubmit later with those fixed.

Score = sequence Recursion number / n (size of the cube),

Doesn't that mean the score will be higher if you prove it for a higher order nxn?

 

[Cuberstache]

Doesn't that mean the score will be higher if you prove it for a higher order nxn?

No, you're diving by n, so the larger n is, the smaller the score will be. (Since n can only be a positive integer)

I meant lower. I thought lower was bad but then I realized that it isn't necessarily true.

Wait... What that does mean is that the lower the recursion number, the better.

I added a clarifying example to the problem 4. It seems that it was not clear that the generator sequences don't have to be simple moves (if you can solve a cube with only 2 algorithms then it's a 2 generator for the purpose of this problem.

Wait... What that does mean is that the lower the recursion number, the better.

No the score for 1.INF is

(Recursion number)  / n

The result of division formula a / b gets bigger when a gets bigger, and gets smaller when b gets bigger.

The intuition is that it's harder to find big recursion number (hence more points for better solution i.e big recursion number) and it's harder to do so on a smaller cube (hence more points for better solution i.e. small n)

number of sequences + (total length of all sequences in HTM) / 100

Just to be clear, don't you mean this: number of sequences + (total length of all sequences in HTM / 100)?

If all your sequences are longer than 25

So all of them cumulatively?

 

[WoowyBaby]

Just to be clear, don't you mean this: number of sequences + (total length of all sequences in HTM / 100)?

Of course, I’m almost certain that’s what he means.

so the whole's place doesn't count for anything if the combined length is > 1.00? Does X.25 = 0.25?

If you have [R, R U2 F U F’ R’ U2 F L D’ R2 U R’ U2 R U R’ U R U2 R2 F R F’ U F, R2], it would be a better score than [R, U2, F, L].

The first example only has 3 sequences, and a total HTM of 28, so the score is 3.25.
The second example has 4 sequences, and a total HTM of 4, so the score is 4.04.
Lower score is better.

I hope that clears up any confusion.

Whoops, I forgot to bump the thread when I turned in my results.

Thats Pretty Good

4.3A) Design a smallest set of generators for the whole cube without allowing the use of rotations (only RLUFDB)

Are initial rotations allowed, or does it have to be in scrambling rotation?

 

[Cuberstache]

Are initial rotations allowed, or does it have to be in scrambling rotation?

It doesn't really matter since you have to solve all possible permutations of the cube with the generator you pick. If you have a scramble, doing a rotation just changes it to another scramble.

 

[TipsterTrickster]

Updated my submission.

 

[brododragon]

Bump. Finished.

 

[WoowyBaby]

I'm feeling a bit better about this now, I am sorry for any negativity. This is really actually a ton of fun and super interesting!

I'm going to resubmit

Edit: Also, if you want more competitors in your Kompetitions, perhaps you could make a post in the Fewest Moves Facebook group, as people that have experience with that generally know more about the cube than those who don't do it. If you don't want to post on Facebook that's your choice, it doesn't really matter, I'm just putting this out there.

 

[brododragon]

Ya, this Kompetition is amazing! There are less questions, but am improved scoring system and I can tell you took multiple hours in each question.

 

[kubesolver]

is anyone still working on their solutions?
