“…Over the past decades, different classes of neural networks have attracted the attention of researchers, due to their wide range of applications in classification, system control, parallel computing, associate memory and optimization problems [10,12,14,15]. Among them, the research on Cohen-Grossberg neural networks is an important topic (see [3][4][5]9,13,19]), since this neural network could include a lot of models from evolutionary theory, population biology and neurobiology.…”
