Flitering for duplicates

[xsrvmy]

There was a post in CF today asking about repeated 2x2 scrambles, and someone found a duplicate 2x2 scramble within the same comp. This should probably be filtered out.

Scrambles ending in the same state but in a different orientation should be considered duplicates. However, whether a scramble that is the same as another scramble applied to a different starting orientation is a dupliate needs to be discussed.

Thanks for reporting this issue! Would you mind sharing the relevant parts of the conversation where this duplication was discussed?

I would be extremely interested to look at the actual competition data for this occurence

This is a duplicate within the same comp someone found. Not even a different alg for the same scramble (although I don't know if 2x2 scrambler randomizes first move).

mysql> select * from Scrambles where scramble="R' U2 F R2 U2 R' U2 R' F R F";

scrambleId	competitionId	eventId	roundTypeId	groupId	isExtra	scrambleNum	scramble
147189	IndianNationals2015	222	d	J	0	3	R' U2 F R2 U2 R' U2 R' F R F
147238	IndianNationals2015	222	d	Q	0	3	R' U2 F R2 U2 R' U2 R' F R F

Credits to Tim Reynolds for find this

Could anyone have gotten both of these solves? (Does roundTypeId indicate which round?)
