Octopus Mutation Methods (Alternative Polynomial and HypE)

Hello all,

I’m researching Octopus’s optimization parameters. I assume “Reduction” relates to the elite strategy (SPEA-II/HypE), but I’m unclear on the specific mutation types.

I understand the standard Polynomial mutation, but does anyone know the specifics of Alternative Polynomial or HypE within Octopus?

Thanks in advance for any information!
