Evolutionary Strategies: third generation?

The particular feature of mutation in ES is that the step sizes are also included in the chromosomes and they themselves undergo variation and selection; genetically it is represented by promoter. It can be called the second generation of evolutionary computing, we can say that the third generation will be taking into account the fact that not just the gene, and controlling area, called promoters, face mutation and selection, but also the communication between the genes, called gene regulatory networks, also known as transcription networks.
