Random Cubing Discussion

[Lucas Wesche]

Was I the only one who did 2 Look PLL with EP->CP instead of the other way around?

I did 2 look PLL in this way too

Just had one of those rare solves where I did the last layer with an Orientation alg, then another Orientation alg because the first one was a mistake, then a Pll-Skip. Accordingly, I call this the OOPS method.

wow i do that all the time. i like the name of that.

Would anyone like to come up with a creative name for this COLL and its mirror? I'm coming up with a ZBLL U alg list and I've sorted them by COLL, with a name for each (2GLL, Diagswap, double bars, checkerboard are the 4 that I have used) and I'm clueless as to whats a good name for those 2 remaining COLLs. Help?

Sorry, but in 2 look PLL we do corners first and then edges. I dont know EP or CP full forms

Question: 4x4 Colour Neutral vs Solving white and yellow all the time?

You can just as well do 2-look PLL solving edges first and then corners

I call them slash and backslash.

Edit: I should add that I didn't come up with this, but I can't remember where I got it.

Anyone knows if cubesmith's bright blue peels off as much as their standard blue?

Why are movecount measurements all metric? For example: stm, obtm, qtm, htm. What would happen if stm was imperial?

what do you mean?

Here's an optimal random state Pyraminx scrambler in Javascript.
Only 926 bytes (!!!) without the <script> tags.

<script>document.write(function(){r=Math.random;var x=[],y=[],t="0103",u="3524",v="1245",w="1203",p=o=0;for(f=360;f--;){x[f]=[];for(g=4;g--;){d=f;e=[5,4];for(a=3;a<7;a++){e.splice(d%a,0,6-a);d=0|(d/a)}c=e[t[g]];e[t[g]]=e[u[g]];e[u[g]]=e[v[g]];e[v[g]]=c;for(a=0;a<4;a++){d*=6-a;for(c=0;c<6;c++){if(e[c]==a)break;d+=e[c]>a}}x[f][g]=d}}for(f=2592;f--;){y[f]=[];for(g=4;g--;){e=[];d=f;for(a=e[5]=0;a<5;a++){e[5]^=e[a]=d%2;d>>=1}for(a=6;a<=9;a++){e[a]=d%3;d=0|(d/3)}e[g+6]++;c=e[t[g]];e[t[g]]=e[u[g]];e[u[g]]=e[v[g]]^1;e[v[g]]=c;e[w[g]]^=1;for(a=9;a>5;a--)d=d*3+e[a]%3;for(a=5;a--;)d=d*2+e[a];y[f][g]=d}}while(p+o==0){p=0|r()*360;o=0|r()*2592}for(f=0;;f++)if(g=q(p,o,f,-1,"")){for(a=4;a--;)0|3*r()&&(g+=" "+"rulb"[a],0|r()*2&&(g+="'"));return g}function q(j,k,l,m,n){if(l){var a,d;for(d=0;d<4;d++){if(d-m){b=j;c=k;for(a=0;a<2;a++){b=x[b][d];c=y[c][d];if(e=q(b,c,l-1,d,n+"ULRB"[d]+(a?"'

Anybody know what happened to Ian Bourn's 3x3 UWR? It disappeared from the wiki.

 

[qqwref]

Looks like FailCuber removed it. Who's Ian Bourn?

EDIT: The only confirmation of the 3.63 that I can find is this old deleted wiki page http://webcache.googleusercontent.c...ndex.php/Ian_Bourn+&cd=10&hl=en&ct=clnk&gl=us which looks like Ian wrote it himself. Considering this is a very lucky solve I don't think it should really be counted, if it is even true, which I'm not so sure of (30 moves in 3.63 seconds, on an unknown scramble with an 8 move cross?).

It was discussed in one of the facebook groups. Kennan and some others know him and/or think it's legitimate. I don't know details, though.

Yeah I know Ian and have good reason to believe it's legit. He hovers around 9-10 seconds usually and as you probably know, the solve was really lucky/easy. His comp avg is only low 11 because he doesn't get to compete much/gets really nervous.

I'm the one who removed it. I removed it because he was insulting Randommo
and I deleted the single because he is obviously a troll.

Except that he is (pretty much) sub-10 and may well not be a troll.

EDIT: Also, isn't the UWR like 3.5something by Riley Woo?

Yeah, this isn't even the UWR...
