There are no algs basicly because the first layers until the last one can be done intuitively or using commutators. You may however learn something useful for the first layers at Kirjava's website :
http://snk.digibase.ca/k4/index.htm . Visit steps 2 to 6 to learn the first layers, then the 7th step is aimed to the last layer.
You won't obviously need all the algorithms written there, but it would be pretty good to learn some 2 and 4 cycles.
I also recommend you to check Dan's K4 ELL video tutorial, that can be found here :

Hope I helped enough!
