The CEC 2019 in Wellington, NZ, gave me a great chance to get absorbed in computational intelligence, really. I enjoyed talking with brilliant people whom I first met inside and outside sessions. A tutorial on PSO given by Prof. AP Engelbrecht was really great and very much well organized to let me know what PSO can do and cannot. I confess that I could first understand what PSO can do really this time thanks to his guidance. I'm happy to have been there at the Conference. I would be back to it again, surely.
