[Boost-users] High memory requirement of adjacency_list

11 Apr 2006

      Hi,

It seems that adjacency list takes up lot of memory than what I was expecting.
Below is the code that I used for testing. 

int main()
{
        typedef boost::adjacency_list<> graph_t;

        graph_t g(6045064);
}

The graph populated is taking about 190MB of memory, i.e., 32 bytes/vertex
approx. I was expecting it to take 4 bytes/vertex.

Am I doing something wrong? My intent is to use "vec_adj_list_impl" having no
properties at all.

Thanks & regards,
Pratyush
