John E. Hopcroft

I need to make it clear right at the beginning that this is a review of the first (1979) edition of this book. It's my understanding that the second edition is better.
I knew that this book was going to be difficult; it's more advanced than I'm really capable of. Which made it all the more discouraging that very early on (page six), I came across a pretty serious typographical error. Now, with this particular error it was fairly easy for me to figure out what went wrong, and what the correct reading was. But now I have a problem: the next time I come across something that I don't understand, something that seems not to make sense, I won't know, I will have no way of knowing, whether it doesn't make sense because it's an error or if it doesn't make sense because I haven't worked hard enough to understand it.
Then I get to the exercises for chapter one. They give answers to selected exercises, those "whose solutions are particularly instructive". Well, the first exercise they give a solution to is of the "prove this statement is true" sort. And I'm pretty sure that, while the statement is true, the proof they offer in the solution is not complete.
These are problems that make this book highly frustrating for me.… (plus d'informations)
