What is better, adjacency lists or adjacency matrices for graph problems in C++?
... a list takes up more memory than a matrix:
8e > n2/8 when d > 1/64
So with these numbers (still 32-bit specific) the breakpoint lands at 1/64.
If the density (e/n2) is bigger than 1/64, then a matrix is preferable if you want to save memory.
You can read about this at wikipedia (artic...
