Layer-by-layer

Postby abcd1019 » Tue Jan 24, 2012 7:46 pm

Hello again, and happy <insert (all holidays that passed between the time I last posted and now) here> to you all.

I have a bit of a question again.. I normally solve a normal Rubik's cube using a layer-by-layer method (Solve 1st layer, then 2nd, then 3rd to finish off the cube)
Can the same or similar be done for, say, a 7x7x7? (Solve 1st layer, then 2nd, 3rd, 4th, 5th, 6th, and lastly 7th to solve the cube)
Or maybe even 5x5x5. I'm not sure this method would do too well whenever working w/even-numbered cubes.

The quick answer is... yes. Would I attempt it...? No. Reduction method for me. Converting each extra layer so that the whole thing behaves as a big 3x3 by matching centres and then edges, and fixing any parity along the way.
Please take off topic discussion off this forum. Thanks.

Yeah, I was just wondering because reduction still confuses me.
Given a bit of time, I can do the centers, but the parts about fixing parity mistakes and edge-pairing is where you lose me.
I can do the first layer of 5x5x5 or 7x7x7, but I wouldn't know about the rest.

It can be none, but probably not efficiently. It takes me around 3 to 4 times longer to do 4x4x4 layer by layer than reduction method.
lol, here to help ^_~

Lastly, is reduction supposed to be a method entirely based on common sense and a keen eye, not really any algorithms to use?

Have a look at my 4x4 and 5x5 guides in the solutions board for more info on reduction.

I solved my 4x4 Cube layer by layer (without looking to any solution), and it was quite hard.

It is a nice experience, but it just depends on what you are looking for.
