ACO-based approaches: The ACO algorithm is inspired by ants behavior in determining the optimal path from the nest to the food source. The algorithm becomes popular after Dorigo et al. work was standardized in IEEE [63],[64] and [65]. With the progress of time Dorigo′s book on ACO [66] and survey paper[67] are heavily cited by the researchers and scientists in this field. The cluster analysis algorithms based on ACO follow either of the two fundamental natures of real life ants.
