4*4*4 ELL algs

[deadalnix]

I'm thinking to solve my 4*4*4 using VH system. I want to ignore the parity problem exept in the last step : ELL.

I found some algs on dan harris cube page : http://www.cubestation.co.uk/cs2/index.php?page=4x4x4/paritypll

But I'm looking for the cases with OLL parity. My research are useless, and i have no idea how to find my own algs.

Maybe using Acube, whith spécifics parameters ? Maybe somebody have already done the work ?

How Dan's algs come from ?

you can solve all parity cases intuitively as long as you know all the parity algs. Those on Dan's page are just examples of what cases could come up. For OLL if there is a Odd number of edges oriented just do the OLL parity algs and continue solving as if solving a 3x3x3 for PLL parity if you are sure that if is not a PLL cases on a 3x3x3(you should have memorized all PLL by now) just apply parity and solve the case

r2 (Uu)2 r2 b2 U' r2 (y) r2 U r2 (Uu)2 (y') r2 <= this is intuituive ?

I think I have not enought intuition

In fact, as written in the topic title, I'm not looking for PLL algs, but ELL. And the algs become realy un-intuitive if an edge isn't flipped correctly. I know 2 of them for the moment, but I'm looking for the others :

x'r2U2'xU2'lU2'r'U2rU2'xU2'rU2'l'D2r2x'
and
x'r2U2'xr'U2r'U2x'U2r'U2rU2'r'U2r2U2'x

Where does these alg come from ? And where/how can I found other algs of this type ?
