Nature as a source of inspiration has been shown to have a great beneficial impact on the development of new computational methodologies. Algorithms that mimic biological systems can create new paradigms for computation, such as neural networks, evolutionary computing, and swarm intelligence. Biologically inspired algorithms (BIA) comprise a class of stochastic optimization and adaptation methodologies, designed for global optimization. One of the most promising biologically inspired algorithms is the evolutionary algorithm. The great majority of evolutionary algorithms extracts inspiration from the process of genetic evolution. In Darwinian evolution, species selection is based on their capacity for survival of the fittest in an ecosystem. Under this view, classes of evolutionary algorithms, known as genetic algorithms, genetic programming, and evolutionary programming, have been developed. All classes of evolutionary algorithms share a large number of characteristics (Heberlé & De Azevedo, 2011). We have been working in the application and development of bio-inspired computation to assess the problem of protein-ligand interactions (Xavier et al., 2016Heck et al., 2017de Ávila et al., 2017Pintro & Azevedo, 2017).
