1. The Social Insect Metaphor Adam Dennis, Kate Patterson, Curtis Sanford, Andrew Vanderveen

2. Rationale Intelligent packets, called “Ants”, that interact to keep the contents of the routing tables up to date. These Ants are only capable of simple stochastic decisions influenced by the availability of previously laid stigmergic, volatile trails.

3. Goals of Ants To reach the “food” (destination), and make a successful return path

4. Drawbacks On encountering multiple stigmergic trails, an Ant will probabilistically choose the route with greatest stigmergic reinforcement. Naturally, this will correspond to the ‘fastest’ route to the food.
