What are the advantages of CECA over ECA?

[13299118606]

I'd like to know what improvements CECA has made and what advantages it has over ECA. Are there any corresponding references to the algorithm? https://github.com/jmejia8/Metaheuristics.jl/blob/master/src/algorithms/singleobjective/ECA/CECA.jl

Violation sum of constraints are used to produce the centers of mass (in addition to objective values). No, there aren't references yet.
