A combined process algebraic, agent and fluid flow approach to emergent crowd behaviour [PDF]
, 2010 Emergent phenomena occur due to the pattern of non-linear and distributed local interactions between the elements of a system over time. Surprisingly, agent based crowd models in which the movement of each individual follows a limited set of simple rules
