RT Journal Article T1 Bio-inspired computation: Where we stand and what's next A1 Del Ser, Javier A1 Osaba, Eneko A1 Molina, Daniel A1 Yang, Xin She A1 Salcedo-Sanz, Sancho A1 Camacho, David A1 Das, Swagatam A1 Suganthan, Ponnuthurai N. A1 Coello Coello, Carlos A. A1 Herrera, Francisco AB In recent years, the research community has witnessed an explosion of literature dealing with the mimicking of behavioral patterns and social phenomena observed in nature towards efficiently solving complex computational tasks. This trend has been especially dramatic in what relates to optimization problems, mainly due to the unprecedented complexity of problem instances, arising from a diverse spectrum of domains such as transportation, logistics, energy, climate, social networks, health and industry 4.0, among many others. Notwithstanding this upsurge of activity, research in this vibrant topic should be steered towards certain areas that, despite their eventual value and impact on the field of bio-inspired computation, still remain insufficiently explored to date. The main purpose of this paper is to outline the state of the art and to identify open challenges concerning the most relevant areas within bio-inspired optimization. An analysis and discussion are also carried out over the general trajectory followed in recent years by the community working in this field, thereby highlighting the need for reaching a consensus and joining forces towards achieving valuable insights into the understanding of this family of optimization techniques.
