MOO for GA

[Collin Price]

Hey all,

Is it possible to have a single population with multiple objectives? The only examples I have been able to find are VEPSO related and it looks like its implementation is specific to having multiple populations with individual objectives.

Thanks

Hi Collin,

Yes, there are a number of PSO algorithms to solve MOO problems using only
one population. Here are some references:

Thanks Andries! Those papers have been very helpful. I was actually looking to see if CILIB supported this feature out of the box.

Thanks Andries! The papers you have provided were very helpful. I was actually looking to see if CILIB supported this functionality. From what I can tell the only MOO implementation is for VEPSO.
