[閒聊] 最近發生的墨西哥選手4.41秒事件

[yock6411 (Osis+)]

事情是發生在今年5/25的墨西哥Perry公開賽

有位平均約16秒左右的選手Julio

在3x3初賽第一輪就轉了4.41秒

隨後WCA也對此展開調查 以確定是否有作弊行為

就在6/7這天

Tyson在WCA論壇上發了一篇公告

我翻譯了一下內容

大致上是這樣子的

Dear WCA Community,

親愛的WCA社群們

This notice is in regards to the Perry Open 2013 competition held in Distrito
Federal in Mexico on May 25, 2013 with Uriel Gayosso Ruiz acting as WCA
delegate. During the first round of the 3x3x3 speed solve competition,
competitor Julio Martín Gómez Telésforo (2011TELA01) recorded the
following average of five solves: (4.41), (18.90), 14.71, 18.68, 16.53.

這個公告是有關於5/25在墨西哥聯邦區舉辦的2013 Perry公開賽的事情，這場比賽的WCA
觀察員是Uriel Gayosso Ruiz。在3x3雙手項目中的第一輪，有位名為Julio Martin
Gomez Telesforo的選手(WCAID : 2011TELA01)，他的五轉平均成績是 :
(4.41),(18.90),14.71,18.68,16.53

The IAC completed its own independent investigation of this incident and the
competitor (2011TELA01) confirmed to the IAC that his solution for the 4.41
second solve was:

獨立顧問委員會(IAC)針對這個事件進行了獨立的調查，而且Julio向IAC確認了他4.41秒
那轉的解法，解法如下：

x2 U' R D F2 R L B' D2 L U' B2 U F' L' U2 D' B' U' U B' + J-permutation

x2 U’ R D F2 R L B’ D2 L U’ B2 U F’ L’ U2 D’ B’ U’ U B’ + J-perm(PLL
case)

where a J-permutation is a case that can be solved with R U2 R' U' R U2 L' U
R' U' L.

而這個J-perm是可以用R U2 R’ U’ R U2 L’ U R’ U’ L來完成的case

As reported to the WCA by the IAC on May 31, 2013, the competitor insisted
that he solved the cube in this manner. The scramble of the solve in question
as reported by the WCA delegate is:
F2 D2 B2 F2 R F2 L' D2 B U B2 R' F2 U' F' D' L D2

2013.5.31，IAC把調查結果回報給WCA，表示Julio堅持他是用上述這段解法完成方塊的。
經WCA觀察員Uriel的回報指出，這一轉的Scramble為：
F2 D2 B2 F2 R F2 L’ D2 B U B2 R’ F2 U’ F’ D’ L D2

The competitor reports his solution to the above scramble to be:
x2 + [moves improvised by competitor] + J-permutation

Julio聲稱他在這轉的解法是：
x2 + [Julio自己的解法] + J-perm

By applying a J-permutation before the scrambling sequence, we have the
following sequence:

把J-perm的公式加在這轉Scramble前面，就得到了下列這段轉法序列

(R U2 R' U' R U2 L' U R' U' L) x2 (F2 D2 B2 F2 R F2 L' D2 B U B2 R' F2 U' F'
D' L D2) x2

(R U2 R' U' R U2 L' U R' U' L) x2 (F2 D2 B2 F2 R F2 L' D2 B U B2 R' F2 U' F'
D' L D2) x2

The solution to this state produces a sequence of moves that solves the
original scramble into a J-permutation.

用這樣的解法可以把原本的scramble解到剩下一個J-perm的情況

The optimal solution found by Cube Explorer for this sequence is:

然而用Cube Explorer分析出最佳化的解法是：

U' R D F2 R L B' D2 L U' B2 U F' L' U2 D' B2 (17f*)

U' R D F2 R L B' D2 L U' B2 U F' L' U2 D' B2 (17f*)

and the improvised moves reported by the competitor are:

而Julio回報給IAC的解法是：

U' R D F2 R L B' D2 L U' B2 U F' L' U2 D' B' U' U B'

U' R D F2 R L B' D2 L U' B2 U F' L' U2 D' B' U' U B' (根本就只是多了U’ U這兩
個贅步)

which is identical to the optimal solution found with some minor adjustments
made at the end.

與最佳化解法幾乎一樣，只有在後面稍微加了一點小贅步掩飾

The solution presented here is suspicious in several regards. First, the
solve does not match previous descriptions of the solution made by the
competitor after the competition. Second, the solve matches output from an
optimal solving software, does not resemble any known solving method, and
does not have any logical flow. Finally, the solve proposed does not seem
amenable to executing in under 4.41 seconds, as claimed by the competitor,
due to multiple turns on each face of the cube. Given this information, we
find that the competitor did not solve the WCA generated scramble for the
round in question in 4.41 seconds by either the solution presented here or by
any other solution.

在這裡提到的解法有多個懸疑點。第一，這轉的解法和Julio在比賽之後所描述的解法並
沒有相符。第二，這轉的解法跟用軟體跑出來的解法一模一樣，而且沒有辦法辨別出有使
用任何一種解法(比如說有些人可以辨識出他是CFOP、LBL、Roux等等，但這個轉法不行)
，也沒有任何符合邏輯的流程。第三，Julio聲稱的這段解法似乎不可能在4.41秒轉出來
，理由是解方塊的時候轉動到太多不同的面了。鑒於上述的資訊，我們發現Julio在具有
爭議的4.41秒這一轉，並沒有使用在此提到的這種解法或是其他解法來完成這顆方塊。

The WCA finds that competitor Julio Martín Gómez Telésforo (2011TELA01)
has maliciously exploited the WCA and the organizers of Perry Open 2013 and
declares that the 3x3x3 speed solve in 4.41 seconds is invalid and will be
recorded as a DNF. Due to the dishonesty of the competitor, and the attempted
exploitation of Perry Open 2013 and the WCA by the competitor, the WCA
prohibits the competitor Julio Martín Gómez Telésforo (2011TELA01) from
participating in any WCA events through December 31, 2015.

WCA發現Julio惡意利用了他們和2013 Perry公開賽的籌辦者。在此WCA宣布4.41秒這轉屬
於無效，並且將紀錄修改為DNF。針對Julio的不誠實，以及企圖利用2013 Perry公開賽和
WCA的行為，WCA將禁止Julio參加任何WCA的項目，直到2015.12.31為止。

The WCA urges all WCA delegates and organizers to remain vigilant in their
tournament operations.

WCA在這裡叮嚀所有觀察員和比賽籌辦者，必須在比賽中保持警惕。

The WCA thanks the IAC for its diligent work, and to the community members
who supported the IAC's investigation.

WCA也感謝IAC的幫忙，以及其他協助IAC調查的成員。
