WCA目前打算重新訂定Regulations還有Guidelines 目前初稿如下：有興趣的人可以花些時間看一下，然後有什麼建議可以跟我說，我再反應上去。 (因為很長，所以我分兩篇來po) # WCA Regulations 2012 The WCA Regulations are supplemented by the WCA Guidelines. To make the Regulations and Guidelines easier to read we use "he" where the reader should read "she or he". The use of the words "must", "must not", "shall", "shall not", "should", "should not" and "may" comply with RFC 2119. ## Article 1: Officials - 1a) A competition must include a WCA Delegate and an organisation team (consisting of one or more individuals) with the following officials: judges, scramblers and score takers. - 1b) The organisation team of a competition is responsible for logistics before and during the competition. - 1c) The WCA Delegate may delegate responsibilities to other members of the organisation team, but is ultimately accountable for how these responsibilities are carried out. The WCA Delegate for a competition is responsible for: - 1c1) Reporting to the WCA Board regarding adherence to WCA Regulations during the competition, the overall course of the competition, and any incidents. The report must be submitted to the WCA Board within one week of the competition date. - 1c3) Sending the competition results to the WCA Results Team. - 1c3a) All scramble sequences used during a competition must be sent with the results of the competition. - 1c3b) Scramble sequences must be labelled with the events, rounds, and heats for which they were used. - 1c4) Sending corrections to the competition results to the WCA Board. - 1c5) Advising the other officials where necessary. - 1c6) Approving all events and round formats of a competition, before the competition starts, and if changes are required during the competition. - 1c7) Decisions about disqualifying competitors during the competition. - 1c8) Providing the scramble sequences. - 1c9) Decisions about changes to the scheduled times of rounds.

All timed averages and means under 10 minutes are measured and rounded to the nearest hundredth of a second. - 9f2) All timed results, averages, and means over 10 minutes are measured and rounded to the nearest second (e.g. x.4 becomes x, x.5 becomes x+1). - 9f4) The result of an attempt is recorded as DNF (Did Not Finish) if the attempt is disqualified or unsolved/unfinished. - 9f5) The result of an attempt is recorded as DNS (Did Not Start) if the competitor is eligible for an attempt but declines it. - 9f6) For "Best of X" rounds, each competitors is allotted X attempts. The best result of these attempts shall count for the competitor's ranking in the round. - 9f7) For "Best of X" rounds, a DNF or DNS is the worst possible result. - 9f8) For "Average of 5" rounds, competitors are allotted 5 attempts. Of these 5 attempts, the best and worst attempts shall be removed, and the arithmetic mean of the remaining 3 attempts shall count for the competitor's ranking in the round. - 9f9) For "Average of 5" rounds, one DNF or DNS is permitted to count as the competitor's worst result of the round. If a competitor receives more than one DNF and/or DNS in the round, his average score for the round is DNF. - 9f10) For "Mean of 3" rounds competitors are allotted 3 attempts. The arithmetic mean of the 3 attempts shall count for the competitor's ranking in the round. - 9f11) For "Mean of 3" rounds, if the competitor scores at least one DNF or DNS, his average score for the round is DNF. - 9f12) For "Best of X" rounds, rankings are assessed based on the best result per competitor. The following shall be used to compare results: - 9f12a) For timed results, "better" is defined as the shorter time. - 9f12b) For Fewest Moves Solving, "better" is defined as the shorter solution length. - 9f12c) For Multiple Blindfolded Solving, rankings are assessed based on number of puzzles solved minus the number of puzzles not solved, where a greater difference is better. If the difference is less than 0, the attempt is considered unsolved (DNF). If competitors achieve the same result, rankings shall be assessed based on total time, where the shorter recorded time is better. If competitors achieve the same result and the same time, rankings shall be assessed based on the number of puzzles the competitors failed to solve, where fewer unsolved puzzles is better. - 9f13) For "Mean of 3" and "Average of 5" rounds, rankings are assessed based on the ordering of the averages/means of the competitors, where "better" is the shorter recorded time. - 9f14) For "Mean of 3" and "Average of 5" rounds where two or more competitors achieve identical average/mean results, rankings are assessed based on the best result per competitor, where "better" is defined as the shorter time. - 9f15) Competitors who achieve the same result in a round receive and identical ranking for the round. - 9g) A Combined Round consists of two phases of attempts, where competitors advance to the second phase if they meet a designated cutoff during the first phase. - 9g2) Whether a competitor proceeds to next phase of a Combined round, must be decided by ranking (best x competitors) or by result (all competitors with a best result under x) of the first phase. - 9i) Results of official WCA competitions must be listed on the WCA world rankings. - 9i1) The WCA shall recognise the following types of regional records: national records, continental records, and world records. - 9i2) Results of official WCA competitions are dated to the calendar date of the competition.

The cutoff must be specified before the preceding elimination round starts. - 9p3) If a qualifying competitor withdraws from a round, he may be replaced by the best-ranked competitor below the cutoff from the preceding round. - 9r) A qualification round must be held before the first round of the event. - 9r1) When announcing an event, the organisation team must include: - 9r1a) Any limit to the number of competitors permitted in the first round of the event. - 9r1b) Any limit to the number of competitors permitted in the qualification round of the event, and any limit tothe maximum number of those competitors who will proceed to the first round. - 9r1c) The average/mean result or single solve result, achieved in previous competition, required to qualify directly for the first round of the event. - 9r1d) The latest permitted date used to determine the qualifying average/mean result or single solve result on the WCA rankings. - 9r2) Each competitor of an event who has not directly qualified for the first round of the event must compete in the qualification round in order to participate in the first round. - 9r3) A qualification round may be added to accommodate newly registered competitors, and/or the maximum number of competitors in the qualification round or first round of an event may be increased. These changes must be made at least two weeks before the competition. - 9s) Each round of each event shall have a time limit (see Regulation A1a). ## Article 10: Solved State - 10b) Only the resting state of the puzzle, after the timer has been stopped, is considered. - 10c) The puzzle may be in any orientation at the end of the attempt. - 10d) All pieces of a puzzle must be fully attached to the puzzle in their required positions.

An appeal does not guarantee the competitor an extra attempt. - 11e1) If a competitor is awarded an extra attempt, the extra attempt must be scrambled using a different scramble sequence. This scramble sequence must be generated using the current official version of the official WCA scramble program (see Regulation 4f). - 11f) The WCA Delegate must not support his decisions with video or photographic analysis.
