Winter Variation Corners Permute, abbreviated as WVCP, is a subset of CLP used for orienting and permuting the last layer corners during insertion of the final F2L slot while preserving Edge Orientation.
WVCP may only be used in last slot cases where the final corner-edge pair are already connected in the U-Layer. In the R U R' case, SVCP can be applied. After using WVCP, all the corner pieces will be correctly oriented and permuted in the last layer.
There are 189 WVCP algorithms total(excluding mirrors), one for each combination of corner orientation and permutations. WVCP cases are set up so there is a corner-edge pair in the top layer to be placed in the final slot.
