大家都写了很多技术贴。我也发个高级解法。不过估计很多人都没有兴趣学- -(如果二阶你想sub3,你一定要学!)




感谢2rabbits提供公式网页!我正在学这个方法、各位高手们有兴趣可以跟我一起学。~~



先发一段原文介绍:

COLL stands for Corners and Orientation of the Last Layer.  It is a set of 40 algorithms that orient and permute corners without affecting edge orientation.  What that means is if your LL edges are already oriented and you use COLL, there is an 8/12 chance you will end with a U perm, a 2/12 chance you will end with a Z perm, a 1/12 chance you will end with an H perm, and a 1/12 chance you will skip PLL entirely.  I recommend learning it (or at least parts of it) after you have mastered OLL.  I also highly recommend learning this if you plan on learning ZBLL.  You should also definitely learn these algs if you solve with the Petrus method.

COLL is broken up into 7 orientations.  Once you determine what orientation you have, you have to recognize the corner permutation.  There are a few ways you can do this.  You can simply look at the corners and determine what needs to go where.  This is fine, but it takes too long in my opinion.  I use the "code" recognition method.  It looks hard, but it is actually rather easy.  It is a bit hard to explain though.  Basically, with every orientation there are four stickers you are going to look at, and you are going to determine the relationship those four stickers have with each other.  For example, say you had the U orientation.  In this case, you look at the ULB, URB, FUL, and FUR stickers.  The code might look something like this:


All this means is the ULB and URB stickers are opposite colors, and the FUL and FUR stickers are the same colors.  The letters don't literally mean "left", "right", and "front".  It is just a way to denote if the stickers are opposite colors or the same color.  Note that the code could also look like this:


That means the exact same thing as the grid above it.  Again, the letters are just there as a way to denote if the stickers are opposite or the same.

Hopefully that clears up some of the confusion.  If it still doesn't make sense, try setting up some of the cases and comparing the code to what the stickers are.  Hopefully it will start to click.

For the L orientation, I highly recommend learning the cases from two angles, because 3 of the 6 algs start with U2.  So the first move for those cases may or may not be necessary, depending on the angle you are doing it from.  You should also be able to recognize the Pi and H cases from any angle pretty easily.


然后就是公式。我整理了的、在附件里。~

另附2rabbits发的COLL四个观察法。我研究了一下、主要是利用了相反色&相同色&不同色的概念。对整个EG解法都很有用处呢~

EG还是个很不错的解法。只不过Erik旧站还是不完善。我打算用软件算一些公式之后优化。到时再贡献给大家~

很好很好
二阶版块 一天3个技术贴

晕!

话说 你这个公式 是适用于三阶的
二阶专用公式的步数都很短的

ERIK的旧个人网站上有
去上speedsolving 论坛看看吧

我觉得其实没有这么麻烦,
只要熟悉二阶每个OLL都是哪两个棱互换,
就可以退出做完O之后的第二层状态了
明天我再研究一下,看看能不能总结出一整套规律来

嗯~都发出来吧。不要有什么保留、传播出来大家分享。中国的水平才能提高一截儿。~

下载下来看看,希望给我惊喜。
2#的不要藏私了,有好东西发出来看看呗、、别光说有,就自己看、

如果这真是三阶专用的COLL的话,那就肯定还有改进的必要了,而且在二阶方面,COLL和CMLL的效果完全一样,那桥式的玩家(背完CMLL)就没必要看了吧?

新买的二阶,好好研究研究

看了楼上各位说的,就不打算学习这个了
