Hello all:

First of all, I’ve been trying to learn Boost Library usage and I’m very new to this topic!!!!!

Now a simple question: In the book “The Boost Graph Library,” TimePropertyMap has been used to keep track of the discovery time for each vertex (p116, Backtracking Graph Search). I fail to understand how this property map should be defined. Could anybody please explain to me what exactly is a property map and how it should be defined in this particular case? Thanks in advance.

Abhi

Carefully read section 1.2.2 Property Maps starting page 6. Then read page 63 bottom half. This is a *critical* point. Then read page 53 bottom half. Yes, read page 63 *before* 53. You have to read the beginning of this book very thoroughly it is very complex. You can't just jump in in the middle. Hope that helps! Scott
