Hi I need to write a paper about the performance of different neighborhoods
in PSO. I chose ECJ as the tool. How can I change the neighborhood in ECJ? I
read I have to rewrite the assignNeighborhoodBests function. However I dont
have a clue about how to do this. The one used is obviously a ring topology.
 How for instance can I transform the function into a star, pyramid, van
Neumann topology? Is it much effort to do so? Thanks for your help!!!

Or do you have a different tool to suggest where I can simply change topologies?

kind regards
Philipp
