D2 Textbook error?
Hey Guys
I had a problem with Q4 in June 2011,
First of all why is there a dummy of H I to the end, surely no dummy is required as all three of them are going to the final node?
Also why is there a dummy network for A and B. In my text book a similar problem came up up but there was no Dummy network, does this mean the textbook is wrong (Attached is a picture).
