Computer programmers have adapted some ant problem-solving methods to software programs (but without the need for complex chemical scents).
Of course, ants and other animals do not make decisions in a “conscious” manner as humans would. Instead they rely on algorithms.
These elements of harvester ant behavior present a severe challenge for the evolutionary paradigm.
Optimization algorithms enable the ant colony to decide how many ants to send to a given food source and when to drastically reduce the number.
