I think a good way of memorizing is divide the algorithm

into "macros" or finger shortcuts. It also helps to follow what

happens to the first layer as you perform the algorithm. To adjust

the algorithm for your hands, do not be afraid to do some "bold"

things, such as performing the whole algorithm with a cube turned by

180 degrees or even upside down. Sometimes you can twist the cube by

twisting TWO layers with your right hand rather than just one - this

basically twists the cube by 180 degress (a neat trick) without

having the regrip the cube. I am sure you find your own tricks that

will lead to a unique style of yours.

Overall advice, try to "dissect" each algorithm and look at the moves

from different angles to figure out the best way to perform them. I

am not a big protagonist of the idea that there is just one correct

(or best) way to do the algorithms because we are all different and

we develop different twisting styles. Besides, it is soooo nice to

watch other speed cubists how they handle the cube and perform the

algorithms with ease and speed. It never ceases to amaze me to watch

others do their magic with the cube.

Pleasant memorizing wishes

Jessica - I won't say those algorithms are "illogic". In fact, I think that the

permutation algorithms are very simple to learn and as there's only

13 of them (up to isomorphism or 21 if you prefer) you just have to

sit and learn them one by one. Then, you'll see some logic. You

should also read the hints in Jessica's page (a really good page by

the way, thanx a lot) about customizing the algorithms. I learned all

the orientation and permutation algoritms about three years ago. It

took me less then a week to learn the 21 cases for permutation. Then,

I broke my cube and don't touch another one in more then two years!

You know what? Even after two years, I still remember all the

permutation alg. (but I can't say the same thing about the

orientation alg.!). That's what I mean by "you'll see some logic".

When an alg. starts with U, U2 or U', it refers to the picture. It

just means that you don't have to move the U slice to fit the

pictures and then move it again. You were talking about logic, that

is pure logic!

I hope this will help you,

PL

- Thanx larrpas and jessica for your answers... perhaps (ill)logic is

the wrong word but some algs seem to fit both my hands and eye more

than others. I will work on your customizing suggestions...
