A Brownian motion affected by some constraints, not sufficient to bring about full deterministic behavior.
This concept has been introduced by the French biologist P. VENDRYES (1942).
This author gives various examples. One is the register – by himself – of a Parisian taxi driver, who showed the following absolute or relative - constraints upon passengers instructions, or whims:
- remain within the limits of Paris municipality
- respect one way traffic signs and traffic lights
- follow some obliged routes for public transport
- occasional or more or less permanent diversions due to public works
- existence of some focal and thus more frequently asked for destinations: museums, famous monuments, railway stations, hospitals, etc.
A similar model was introduced by W.R. ASHBY in 1956 under the guise of Markov chains and transitions probabilities matrixes – with some quite entertaining examples (1956, Ch.9).
