stigmergy: follow the leader

WARNING: This is an attempt to be a little bit technical.

We now describe the stigmergy among ants, and we present three models: A, B, and C.  The first model, model A, is a set of equations.  This model is considered scientific while models B and C are non-scientific (not sure if B and C fall under the "artistic" category though).

A:
Model A is an abstraction of the foraging behavior of the ants called the ant system.  Imagine that there is an undirected graph G = (V,E) such that V is a set of vertices or points and E is a set of edges.  The state transition rule is given by the following equation:

Equation 1 is the probability that the ant chooses to move to point s given its current position at point r. Note that r and s are elements of V with (r,s) is an element of E.

Through these equations, there is an indirect form of communication through the amount of pheromone on a particular trail, a form of memory not locally stored within the individual ants, and this communication is called stigmergy.

Way of the Wind

A tree on a high cliff faced a strong wind resulting to the dispersal of its leaves into the countryside.  The leaves moved according to the way of the wind and glided above a waterfall, a dense forest, and then a vast plain.  Some of them landed on a river, and the river carried them for several miles until they reached the sea.  The story can go on and on until probably a surviving leaf has circumnavigated the whole world.  So this is an attempt to capture the moment of the tree's confrontation with the wind.
