The Santa Fe Trail problem is a genetic programming exercise in which artificial ants search for food pellets according to a programmed set of instructions.[1] [2] The layout of food pellets in the Santa Fe Trail problem has become a standard for comparing different genetic programming algorithms and solutions.
One method for programming and testing algorithms on the Santa Fe Trail problem is by using the NetLogo application.[3] There is at least one case of a student creating a Lego robotic ant to solve the problem.[4]
