Note to moderator: Read the answerline carefully. Note to players: Description acceptable. This task is the focus of videos posted by OpenAI co-founder Andrej Karpathy on the YouTube channel bad·mephisto. When sight is obscured during this task, the Speffz lettering scheme is used. Efficient methods for this task’s FMC variant include ZB and Roux (15[2])(“roo”). Top brands for this task include MoYu, QiYi (“chee-yee”), and GAN. When performing this task on (15[1])more complex objects, annoying “parity errors” may occur. The highest and lowest times are dropped from (*) five results of this task prior to averaging during WCA competitions. The C·FOP (10[1])method for this (10[1])task ends by “orienting” and “permuting” the last layer after F2L (10[1])(“F-Two-L”) and may start by constructing a white cross. For 10 points, name this task in which algorithms are used to unscramble the colors (-5[1])of a six-sided puzzle. (10[1])■END■ (10[1])
