Computer programmers have adapted some ant problem-solving methods to software programs (but without the need for complex chemical scents):
Navigation expert Eric Cassell, author of Animal Algorithms: Evolution and the Mysterious Origin of Ingenious Instincts (2021), offers some insights in the book into how ants organize themselves using what amount to algorithms, without any central command…
Ants are remarkably consistent in their lifestyle: All of the roughly 11,000 species of ants live in groups, large or small. There are no known solitary ants. Living in groups requires a social group lifestyle that includes “agriculture, territorial wars, slavery, division of labor, castes, consensus building, cities, and a symbolic language.” (p. 85) How is this to be managed by ants with very small brains (200,000 to 250,000 neurons*) and very limited individuality? …
Ants communicate mainly by pheromones, scents that provide information. In their book, The Superorganism: The Beauty, Elegance, and Strangeness of Insect Societies (2008), Bert Hölldobler and E. O. Wilson (1929–2021) identified twelve areas of communication mediated by pheromones, including “alarm, attraction, recruitment, grooming, feeding, exchange of fluids and solid particles, group effect, recognition of nestmates, caste determination, control of other individuals competing for reproduction, territoriality, and sexual communication” (p. 90). What makes pheromones a complex communication system is that most emissions are of several pheromones mingled rather than one only. Some signals are recognized by all ants in the vicinity, others only by the species, and others are specific to a colony. One evolutionary biologist describes the processing of pheromones as equivalent to AND gates and STOP in a computer system. (p. 91). So the ant is not so much thinking what to do as responding to an AI-like signal.

Ant researcher Deborah M. Gordon calls it the … aw, you guessed! … the anternet.
Takehome: Navigation expert Eric Cassell points out that algorithms have made the ant one of the most successful insects ever, both in numbers and complexity. Computer programmers use some of the same basic structures.

Researchers are finding that insects have a number of strategies for making the most of comparatively few neurons to enable complex behavior.
