how do you setting cases?

[chikato_tan]

i`had watched a lot of video about rubik tutorial, for example : f2L , oll , pll(badmephisto) , but i have no idea how does he setting up cases, so please show me , thanks

Just do the Algorithm in Reverse.

For example R U R' U R U2 R' can be reversed as R U2 R' U' R U' R'

Steps
1.Read the Algorithm from the back
2.Replace ' by <no dash>
3.Replace <no dash> by '

1. Input the cube into a program called "Cube Explorer".

2. Select "Add and Generate"

3. Optimize given result by selecting "Optimal".

4. Apply result to cube.

5. ???

6. Profit.

EDIT: Also, if you know a bit of cube theory, if you continue to do that same alg over and over, it will solve itself, and the case which it solves for will appear.

but badmephisto made a video on how to set up cases

Just do the Algorithm in Reverse.

For example R U R' U R U2 R' can be reversed as R U2 R' U' R U' R'

wouldn't R U R' U R U2 R' be reversed as R' U2 R U R' U R?

R U2 R' U' R U' R' would be the inverse of R U R' U R U2 R'

If it's a cycle, do the inverse, otherwise just do the alg again. Not all algs need the inverse to be set up. An example is the t perm.
