Jan 18, 2017 · Ant Colony Optimization The Ant Colony Optimization algorithm is inspired by the foraging behaviour of ants (Dorigo, 1992 ) . Some applications: Protein folding. A first step in this direction has already been made with the application to telecommunications networks routing, but much further research will be necessary. If other ants find such a path, they are likely not to keep traveling at random, but instead follow the trail laid by earlier ants, Ant colony optimization algorithms explained. Marzieh Marzi. Ant colony optimization (ACO) is a population-based metaheuristic for the solution of difficult combinatorial optimization problems. Ant Colony Optimization because it is the problem to which the original AS was first applied, and it has later often been used as a benchmark to test a new idea and algorithmic variants.

Ant Colony Optimization is not just useful for computer networks as discussed in this paper. This algorithm is also being researched at MIT in an effort to steer robotic cars through a busy city. While walking in such a quest, the ants deposit a chemical sub stance called pheromone in the ground. Ant Colony Optimization (ACO) studies artificial systems that take inspiration from the behavior of real ant colonies and which are used to solve discrete optimization problems. An ant (called "blitz") wanders. In their daily life, one of the tasks ants have to perform is to search for foo d, in the vicinity of their nest.
