There are so many different ways one can implement Dinic's, i have come across

1-> **EV^2** - https://github.com/PetarV-/Algorithms/blob/master/Graph%20Algorithms/Dinic%27s%20Algorithm.cpp
2-> **EV*log(maximum edge capcity)** - https://github.com/ADJA/algos/blob/master/Graphs/Dinic.cpp
3-> **EV*log(V)** - http://www.cs.tau.ac.il/~haimk/adv-alg-2013/dinic2013.pdf

Can anyone tell about or suggest some good tutorials where i can learn 
1-> proof of Dinics
2-> proof of its timecomplexity (1st and 2nd types)
3-> implementation of third type(EVlog(V))
