GWO Algorithm

[kingshuk76]

Hi,
I have been using the GWO algorithm and noticed that the position and score for beta and delta don't get updated to the second or third best position (or previous values of alpha or beta) where the iteration constantly generates better value than current alpha.
If the obj function gives a value better than current alpha, shouldn't the current value of alpha get demoted to beta instead of getting lost?

Thanks and Regards,
