This guy is an international treasure
very good video and playlist!
If you have 2 dead ends, I think this method would fail. A better version would be a deadend's probability of going back to itself should be zero.
Brilliant!
hello ! why do you need the vector of all 1s, "e"?
to get a matrix filled with 1/N, so that we can add the teleports to the original matrix (11:50)
Look up the dot product in transpose form
1/n * [ column of 1's] here 1/n is scalar and the dot product will be vector This is done so we can do matrix multiplication as column of some Matrix M should be equal to some Matrix R row
