Reuben's article gives what you may find an interesting insight into your earlier question regarding how the phenomenon of waves manifests from agent based actions. Reuben was concerned with PDEs of the hyperbolic type (like the wave equation) and the work he did with Richard established solutions for these equations via stochastic means.</font></div></div>
