有意向参加最少步比赛的,请通过以下WCA规则的附则E部分和第十二章,了解清楚最少步的规则:
Article E: Fewest Moves Solving 附则E 最小步数还原E1) | Regulations are as described in Article A (Speed Solving).
Additional/special regulations for Fewest Moves Solving are described below.规则见附则 A(速拧)。最小步数的附加/特殊规则如下所述:
- E1a) The maximum length of a solution is 80 (moves and rotations). 解法的最大长度为80步(步数和旋转);
| E2) | Procedure for Fewest Moves Solving: 最小步数还原的程序:- E2a) The judge hands a scramble sequence to all competitors with a print of the scramble position. The judge starts the stopwatch and says 'Go'.裁判把一个打乱算法和一个打印出的打乱状态交给所有参赛者,裁判启动秒表并说“开始”;
- E2b) The competitor has 60 minutes total time for solving the scramble in as few moves as possible.参赛者有 60分钟的时间以尽可能少的步数还原这个打乱算法;
- E2b1) A judge should announce the remaining time after 30 minutes, 50 minutes, 55 minutes and 59 minutes, and 'Stop' at 60 minutes.
裁判应该在 30分钟,50 分钟,55分钟和59时提示时间,并且在60分钟到达时宣布“停”; - E2c) At the end of the 60 minutes the competitor must have his solution written down clearly for the judge, notation according to Article 12. Penalty: disqualification of the solve.在 60分钟到达时,参赛者必须确保已经把他的解法用符号清晰的表示完成并交给裁判,60分钟到达之后,不允许再写任何字符。符号写法参考第十二章,违规将被取消本次还原的资格;
- E2d) The metric to measure the length of the solution, is Half Turn Metric.衡量解法长度的步数单位参见半转规则;
- E2e) The solution of the competitor must not be in any way related to the scrambling algorithm. Penalty: disqualification of the solve.参赛者的解法不能和打乱算法有任何的关联,违规将被取消本次还原的资格;
- E2f) The competitor must be able to give a clear explanation of the solution.当被要求时,参赛者必须能够清楚的说明他的解法思路;
| E3) | The competitor may use the following objects: paper and pen (both supplied by judge), 3 cubes (self supplied), unlimited coloured stickers (self supplied). 参赛者可以使用以下物品纸和笔(均由裁判提供)、三个魔方(自备)、不限颜色的贴纸(自备);- E3a) Penalty for using other objects: disqualification of the solve.如果使用其他物品,将被取消本次还原的资格。
