Definition

Ant colony optimization (ACO) is a population-based metaheuristic for the solution of  difficult combinatorial optimization problems. In ACO, each individual of the population is an artificial agent that builds incrementally and stochastically a solution to the considered problem. Agents build solutions by moving on a graph-based representation of the problem. At each step their moves define which solution components are added to the solution under construction. A probabilistic model is associated with the graph and is used to bias the agents’ choices. The probabilistic model is updated on-line by the agents so as to increase the probability that future agents will build good solutions.

Motivation and Background

Ant colony optimization is so called because of its original inspiration: the foraging behavior of some ant species. In particular, in Beckers, Deneubourg, and Goss (1992) it was demonstrated experimentally that ants are able to find the shortest path...
