CP Method History: I wrote a history of corner permutation (CP) use in methods. Ranging from its use in ZZ to the various CP first methods that were proposed over the years. This post was also responsible for the method merge that resulted in CEOR. The proposal in the main post was to consolidate each of the CP methods that had the same steps into a single method.
ZBLL history: Most in the community assume that ZBLL is a proposal or development from Zbigniew Zborowski and Ron van Bruchem. However, the fact is that the algorithm set already existed for the Petrus method and was developed by Bernard Helmstetter. Ron and Zbigniew had a goal of getting to an all edges oriented last layer in CFOP and so they created the steps of F2L-1, ZBLS, then solve the last layer in one step (overall called the ZB Method). They even specifically mention that they are using Bernard Helmstetter's development for the Petrus method. The community mistakenly named the oriented edges last layer subset ZBLL based on Ron and Zbigniew's ZB method. In this post I go over the history and why I think it may be a good idea to rename the subset.
The Legacy of Petrus: The Petrus method has been the most influential of all upon other methods. I wrote a post that covers the innovations that came from the Petrus method.
