ABOUT
APB efficiently and ergonomically combines EO plus blockbuilding after a 2x2x3 is built. After the 2x2x3 block, all steps can be executed using algorithms. This removes human error and results in consistently ergonomic and efficient solutions.
APB stands for Athefre('s) Pair & Block. Thanks to Ryan "OreKehStrah" Hudgens for the initial name idea to create the acronym and Melkor for the word Pair to more accurately describe the system. Also thanks to Vincent Trang (trangium) for his help in choosing good algorithms, helping show that 1x2x3 > 2x2x3 is a good strategy, and for his batch solver and MCC which was used for the entirety of APB.
