今天逛论坛的时候不小心发现www.speedcubing.com里有个帖子<br>就是<strong>Improvements for M2/R2发帖子人是</strong><a class="bigusername" href="http://www.speedsolving.com/member.php?u=84">StefanPochmann</a><br>不晓得是不是那个写m2r2的人<br><br>原帖内容是<br><div class="smallfont post-title">

<div id="post_message_18266">Try this scramble: U' R' U M' U' R U M<br>
<br>
Usually I'd solve it like this:<br>
U2 M' U2 M'<br>
U R' U' M2 U R U'<br>
x M' U M' U M' U2 M U M U M U2 x'<br>
<br>
Of course the inverse of the scramble is the much better way, directly
solving the next two edges with a simple short commutator. I intend to
use this for the "ugly" targets FU and BD (or UF and DB, depends on
your view), as they're just M or M' away from the buffer, turning these
ugly cases into quite good ones.<br>
<br>
The second improvement idea is to first solve the edges with M2 as
usual, and in case of parity, immediately fix the parity (i.e. solve
the M slice) together with solving the first corner. If the corner
target is in the left slice, use an L turn as setup move and then one
out of three algs (one for each possible corner orientation). If the
corner target is in the right slice, one out of 7 or 9 algs (depends on
whether you allow the UBR corner to be misoriented, like I do so far)
and no setup turns.<br><br><br>还在m2r2学习中~~~不擅自发表意见了。。。=。=b<br>希望对大家有帮助~<br></div><br>

<P>试这样打乱：U' R' U M' U' R U M<BR>通常我这样解它：<BR>U2 M' U2 M'<BR>U R' U' M2 U R U'<BR>x M' U M' U M' U2 M U M U M U2 x'<BR></P>
<P>当然，打乱步骤的逆步骤是好得多的路子，用一简短的转换器（commutator）直接解决下两个棱；我想把这用于“讨厌的”目标FU和BD（或UF和DB，取决于你的观察），它们经M或M'就离开缓冲器（buffer）了，讨厌情况就转成十分好的情况。<BR>第二个改进的想法是，先按通常方法用M2解决几个棱，有奇偶性（parity）时，与解决第一个角一起，立即固定这奇偶性（即解决夹层M）。如果角目标在左片，用L调整一下，再用三种算法之一（一种算法解决各自可能的角向）。如果角目标在右片，则用7或9种算法之一（取决于你是否允许UBR角错向，就像我至今所做的那样），不必调整。<BR></P>
