The CML-Method (Corner-Middle-Layer-Method) is a speedsolving method created in 2020. It's predecessor was the Waterman Method, but CML uses far less algorithms and is effitiently enough to be a speedcubing method.

CML-Method in-depth

Step 1: First Layer (Blockbuilding or LBL approach) Step 2: COCP-LL (Corner Orientation Corner Permutation Last Layer) (done on the last layer) Step 3: EML (Edge-Middle-Layer) Step 4: PML (Permutation-Middle-Layer)

EML

turn the solved side on the back and insert the remaining edges of the last Layer with U-Perms and F-Moves to insert them, use also S moves or do f moves for better move speed. Sometimes the edges are misoriented (bad egdes in this sense). For these bad edges do: z' 2(M U M U) z

PML

Permutation of the Middle layer is done by a set of 6 algorithms. Only bad edges at the right position: R E' R B2 R' E R E B2 R2 E'

One bad edge and three have to be permuted. Hold the bad edge on the front left position and do for clockwise: U' F L F2 B U R' F' R F2 B' L' U F' counterclockwise: U F U' L F2 B R' F R U' F2 B' L' F' sometimes you have to do then: U2 R B' D R' B U2 D2 F' L D' F L' D2 ( for diagonal orientation of the edges on the Middle layer)

in case of no bad edge, hold the right permuted edge also on the front left side and do: clockwise: U R2 U' D B2 D' counterclockwise: U' D B2 U D' R2

the last case is a swap of two parallel edges: U2 R U' D F L2 D2 R2 B U' D R U2 B2

Pros

• nearly no cube rotations needed
• very fast blockbuilding in step 1
• step 3 can be optimized by some more specific algorithms
• can be used as a beginner speedcubing method
• not much algorithms 20 - 40 (if optimized)
• sub-20 is possible

Cons

• E-moves are not ergonomic
• can be slow on some cases
• a lot of practice is needed to be really fast with this method
