Hi Khurshid,

thanks for your suggestion. I am getting back to C++ after a long break 
writing all my codes in C, so I am a bit rusty !

Do you mean that I would have a set of N elements, one per particle, 
each of which would be a handle that points to the vertex corresponding 
to the corresponding particles? Would the mapping between the elements 
of the set and the positions of the vertex in the graph be preserved 
upon rearrangement of the latter? If you do not mind suggesting a 
minimal code, that would be helpful ! No worries if you do not have the 
time, I will keep digging !

Best,

Julien
